Fitbit Flex Wireless Activity + Sleep Wristband, Black, Small/Large

SUMMARY: This device will not do anything for you, but it will help you make good decisions about what you need to do yourself. Fitness is hard work. If I had to sum up what this device is doing for me, it is this. It is keeping me utterly honest about everything. I cannot lie to myself about how many calories I'm burning. It won't let me. Just knowing there is a record motivates me to make sure it is a good one. It's the same effect one gets if they know they are being graded.  ****** THE LONG VERSION I have been using the fitbit flex for five days now and I have fewer pounds and great fitting pants already, so it would be hard to regret my purchase. I went ahead and set my fitbit up to integrate with MyFitnessPal as soon as I set it up, so I have no idea how it works without it. Setting it up was a breeze. Go here: http://www.myfitnesspal.com/apps/show/fitbit and follow the instructions. Once it is set up it gives you a warning that you should only enter your food on MFP to avoid double entries. I have entered everything I eat on MFP, and the info magically finds it's way to my fitbit dashboard, and there have been no problems whatsoever. Entering exercise is a little more complicated. Once you've done the integration, your MFP exercise entries will require one extra step--the start time of your exercise. My entries consist mostly of running and swimming. Technically, I don't need to enter the runs, since the pedometer takes care of them just fine, but when I do enter a run, the two apps manage it well. MFP gives the start time and duration of the run to fitbit, and fitbit takes that info and does some calculations that take the pedometer data into account, and comes up with a number of calories burned. I have run into one snag...if I edit the start time of my entry in MFP after I've already logged it, it causes the exercise to log twice on fitbit and I have to go into fitbit and manually remove the double entry. Sometimes I'm lazy and I don't enter the runs in MFP and I just let fitbit use the pedometer data exclusively....I've not taken a close enough look at the difference to comment on it, but it seems to work well either way as far as calorie counting. I just prefer knowing the speed and duration of specific intervals and that data is lost if I don't enter it into MFP. I take the flex off when I swim laps, since I have a watch that counts my laps and distances for me and wearing both would be cumbersome. I enter my swims manually into MFP, and fitbit automatically calculates it all. I've had no problems. You'll have a new thing in your MFP display too. Your exercise log will have a "fitbit calorie adjustment" entry. For whatever reason, fitbit lets me eat just a little less than fitness pal does, so the math is obviously a little different on the two programs. If you are tall and have abnormally long legs like me, you may have to adjust fitbit's default stride settings. Their website can tell you how. The biggest lifestyle change for me has been brought about by the in-your-face awareness of just how sedentary sitting at a computer is. On days when I work at my desk, 6PM rolls around and I've only got maybe 500 steps logged. I'll hit the gym to do my 3 mile jog, and still be no where near the 10 thousand step goal that is the default setting for the fitbit, so I end up walking on the treadmill until I get there. I find myself going on long walks after my swim too. Maybe I'm crazy, but I can't stand to go to bed without meeting my step goals first, even if I've logged a long swim, but whatever the reasons, it is working, and fast. I am losing weight again after stalling out for quite a while. I mentioned only having 500 steps after a day at my desk. Yesterday I had my first day away from my desk...shopping, a little yardwork, housework, just getting all the little things that need done around the house...at 5pm I had logged 8000 steps and was almost to my goal. I mention this because I think this is what makes the fitbit worthwhile. It quantifies how sedentary your life is on a given day and then tells you exactly what you need to do to make up for it. And I know, if you are a desk worker like me, that 10,000 steps is going to seem a bit ridiculous after a day at the office, but trust me, if you can make yourself make up for it, you will be blown away by the results. I hesitate to put the numbers down for my weight loss over the last 5 days, because I have frankly lost weight faster than I should and I don't want to invite trolls or create unrealistic expectations...everyone is different. I am eating more than 2000 calories a day (within the recommendations of the app set at medium plan intensity), I'm not starving myself, and yes, my legs were pretty tired the first few days, but I promise, I feel great. I'll be at my goal of 145 in a couple of weeks at this rate. The fitbit didn't lose that weight for me...I worked my butt off all by myself, but fitbit helped me figure out what I needed to be doing. **** I know this review is getting long, but I wanted to mention a couple of other things. I LOVE the sleep monitoring. I have random bouts of insomnia, and I sometimes wake up repeatedly all night, and this thing has done a brilliant job of measuring how much time I've actually spent sleeping vs. how much time I've been in bed. And that number of hours of actual sleep correlates almost perfectly to how I feel, mentally, through the day. The default sensitivity is perfect for me...though I have seen it isn't so much for other people. It is easy to turn it on for naps too. Just tap it five times when you lay down, and again when you get up. You can fix it manually in the website if you forget...it will still have the movement data regardless of whether you tap it or not, it just needs to know when you were sleeping to fix it all. It accidentally goes into sleep mode here and there...once when I was using a hammer drill, once when I was using a hammer, and once when I was shaking a bottle of cat antibiotics to mix it, but when that happens, you know because it vibrates, and if you tap it five times right away to bring it out of sleep mode, it won't mess up your data.

I LOVE love love my Fitbit!! I've had the Fitbit Flex since around February and it has changed my life. The biggest impact it has had on me is that it constantly holds me accountable to my exercise and sleep. I have lost 20 pounds so far, by making diet changes, doing strength training exercises, and moving a lot. The Fitbit would not be nearly as amazing without the technology that goes along with it - the website and the app. When I have bluetooth enabled on my phone, my Fitbit data constantly syncs with my phone. I can check the app to see, in real time, exactly how many steps I've taken, how many miles I've walked, and how many minutes of my day have been "very active". Within the app or the dashboard of the Fitbit website, you can customize your goals for each of these elements. During my first week with the Fitbit, I just went about my normal life and looked at my data at the end of the week. Then I set my goals for the following week to be slightly higher than the amount I did previously. For example, if I did on average 7500 steps a day, then I set my goal for the next week to be 8000 (500 steps more). Every week I look at my data and set new goals to make sure I am constantly improving and moving more. (By the way, I paid the $50 annual fee to sign up for the Premium account. The Premium part of their website provides you with so much data, weekly reports and graphs about your food if you log it, activities, and sleep. You can also download spreadsheets of your data through the Premium tab. I highly recommend this if you are very data-driven or want to keep track of your progress.) One of my favorite features of the Fitbit is the sleep tracker. Since you always wear the Fitbit, it can track your sleep each night, including how long you're actually asleep for, how long it takes you to fall asleep, and how many times you wake up or are restless throughout the night. This is usually the most interesting part of the Fitbit when I show it to friends. I've convinced multiple coworkers to buy and use Fitbits. Fitbits are definitely more fun when you have friends that use it also. You can add friends, and then within the app or website it shows the rankings among you and your friends in terms of who has the most steps. This is REALLY motivating and fun!! Since getting the Fitbits, we are all motivated to walk more and exercise, partially because we want to be in first place in steps. We also now have a reason to talk about our active lives and what we've been up to, and I've even started working out with some of my friends. It's amazing! I've had people ask me how accurate the Fitbit is. While I can't necessarily speak to its accuracy, I can speak to its consistency. That's good enough for me, because what matters to me is that I'm moving and that I'm moving more every week than I did the week prior. I did very recently start having problems with the battery life of my Fitbit. For the last few months that I've had it, I've only had to charge the battery about once every 5 days. I also set up email and text reminders about when my battery is low so that I never let it die completely. (I don't want to lose any steps or sleep data!) When I recently started having this battery life problem, my battery would drain every 12-24 hours. I tried the troubleshooting tips on the website and then sent an email to their customer service team. They were able to check the system logs and verify the battery life error. After sending them a copy of my Amazon receipt, they sent me a brand new Fitbit package free of charge, and without me having to send in my defective tracker first. I have been very impressed every time I've contacted their customer service team. I also contacted them to see if they have any larger size wristbands. The Fitbit comes with a small and large wristband, but the large is definitely not big enough to fit my dad, who is on his own weight loss journey. After emailing them about the larger wristband size, they got my shipping information from me and sent me an extra large wristband free of charge. Wow! Thank you Fitbit! If you're debating whether or not you should spend $100 on this, I absolutely say to go for it. The motivation and information that I've gotten from this device is worth much more than $100 to me personally. If you're someone that would wear a Fitbit all the time, then it's worth it.

Well, the only reason I am not giving this 5 stars is the quality of the wristband. I just got this on May 20th. I was using the small wristband (because, thankfully, both the large and small come in the package). Yesterday I noticed the small band already coming apart a little at the face of it where the hard plastic meets the rubber. So I switched to the large, which is a bit annoying because it is large, but it still works. So I may have to invest in more bands. Regardless, I have been quite religious about keeping track of my food intake, water intake, etc. And I have quite a few friends who also own a FitBit of some sort so, in keeping track of their progress as well, it also motivates me to do more! And I have messaged back-and-forth with a friend or two and my progress is motivating them! Instead of watching TV sitting down, I have my Gold's Gym stair-stepper and I use this to get in a couple thousand steps. Love being able to track sleep as well. I always wondered how effective my sleep was and this answers that question. My sleep is actually quite effective! Unfortunately, there was a bug with my phone (Droid Motorola Rzr M) when they did the KitKat update and the Bluetooth knocks out WiFi so I am forced to get a new, non-Motorola phone, which is okay because I probably needed a new phone. Of course, the Samsung Galaxy S 5 has its' own fitness tracker band (which basically does the exact same thing as the Fitbit except it also tracks ones heartbeat) but I am hoping the FitBit Flex is still awesome with this phone. :) I am sure it will be. (This bug was not taken into account with the 4 stars; that rating is due to the band already starting to wear out.) I have lost about 7 lbs just watching my calories (I was never overweight in the first place but this will help me to stay that way). I recommend this product for anyone who does not have a Motorola Droid Rzr M (or, apparently, any Motorola phone with the new KitKat update) at least until the KitKat bugs are smoothed out. Update: 13 Feb 2015 Still love my Fitbit! One thing though, never put it through the wash - still works afterwards but runs out of battery within 24 hours. So, I went and purchased a new one! The instructions on how to integrate the two are quite easy. I will possibly give the old one to a friend to try. I have inspired at least three friends to get the Fitbit because I lost so much weight! (About 18 lbs now.) I wasn't overweight; just heavier. Believe it or not, I was still in normal BMI, now it is just a lower number, still in the normal range. I purchased a stepper as well (from Amazon, of course) and I have toned up. My husband thinks it's great and has no problem with my spending habits when it comes to my fitness obsession. And this is less expensive than a gym membership (which is also difficult to get to with my schedule). The daily challenges help me and my friends who challenge me to stay on course and strive for the 15K steps a day. I had been keeping track of caloric intake but turns out I don't really eat a lot of calories so I kind of stopped that. But I definitely keep track of water intake. Living in Utah I need to drink a lot of that. Anyhow, I've rambled long enough. Seriously, the Fitbit will motivate you to take those steps and keep in shape.

After reading reviews, both positive and negative for the Fitbit Flex, I decided to dive in and order one. After receiving the package and opening it, I found no instructions other than a handy link on a piece of paper that pointed me to the Fitbit website. No big deal. I found the band, actual Fitbit unit and components of good quality. The unit was completely dead so it needed a charging. I plugged the unit in to the charging cradle and plugged it in and magically a single LED was pulsing! After approximately 2.5 hours, I was greeted with five pulsing LED's and my unit was ready to go. Following the instructions I installed the Fitbit software on my iPhone 5s and paired the unit via Bluetooth. I was happy. My happiness was shortlived, however, as this is when things started to go downhill fast. The Fitbit app guides you through the intial setup, one being entering all your stats into the software. After entering all the pertinent data, I saved the info and went to the dashboard. I was impressed. There were graphs for calories, steps, sleep, etc. For some reason, I decided to look back at my stats and miraculously, I had lost 40 pounds and I was now 10 years younger!! The downside was I was now 0',0" tall and a female!!! I changed my information, saved it. I restarted the app. My age and gender was correct, but now I had lost another 10 pounds! So I thought, maybe three's a charm. I resaved my data one more time and everything fincally stuck....EXCEPT my weight of 230 was now 229.9 lbs. I guess I could live with a tenth of a pound. With my Fitbit on my wrist, I decided to take a few steps around the house. Upon checking the app, it was off by a few steps. Nothing terrible that I couldn't live with. I decided to head to bed as it was 11:45 p.m. to test the sleep function. I crawled into bed and gave the Fitbit the secret knock of taps... Was it three taps? Was it five? Do I tap for 5 seconds? Whatever I tried, the Fitbit would respond with a solitary blinking light. Hmm... I must not be doing something right. I get up, go to YouTube and lo and behold, there's a guy that says you have to tap on the 'curve' of the bracelet to put it into sleep mode. Ah ha!! Now I know the secret. After about 30 minutes of tapping in every possible combination of timing I still could not get the Fitbit to go into sleep mode. The plus side is the dashboard said I burned 500 calories and walked 1200 steps, so I guess I got that going for me. I finally went to bed at close to 2 a.m., frustrated and angry. I then had a thought! I had read you can set the sleep mode in the app! What was I thinking??! All that work to get the unit to go to sleep, when a simple click of a button in the app would solve all my problems. I opened the app, synced the unit and clicked the button to tell the unit I was going to bed. I layed there thinking I wonder what kind of crazy graph I would see in the morning about how many times I tossed and turned and got up to go to the bathroom. Even after getting up twice last night to use the bathroom, I was thinking of how it would look on the graph. After waking up, I promptly opened the app and stopped the sleep function. I had slept a total of 6 hours and 12 minutes. SOLID! I had not woken up or stirred once! The app said I had had the soundest sleep ever!! Needless to say, the Fitbit packed up and will be making the trip back to Amazon for a refund. Not recommended unless you deal well with frustration. Save your money.

***Updated 8-25-2013*** I took a morning walk today and brought the same 3 devices with me that I used in my first comparison. The results were very different and not so good for the Fitbit Flex. Nike+ = 4.02 miles. New Balance Via Active pedometer 4.11 miles. 9665 steps. Fitbit Flex band 3.69 miles??? 8276 steps??? I tend to think the Nike+ app and the Pedometer are closer to correct since the distances they measured are very close to each other. I have walked the neighborhood before too and think from previous experience that I was right near 4 miles. If that's the case, then why is the Fitbit Flex so low compared to the other two? The Flex battery is fully charged, I just charged it last night. And the numbers are the most recent as I synced the Flex to the computer as soon as I got into the house from the walk. What's more confusing is that originally, I was finding that on a daily basis, the Flex was giving me more steps then I normally took. It still does. So this morning's result is pretty shocking. I definitely have to change my thinking that the Fitbit Flex is to be used more to give you a VERY GENERAL idea of how much you have done and not trusted to give an accurate accounting. Addressing something I said in the original review, Fitbit did send me an XL sized band when I requested it. I did wear the Flex on my left arm (non-dominant) next to my watch for a few days, I did not find any appreciable change in the readings the Flex was giving me. So I am back to wearing it on my right arm (dominant) for comforts sake. On the plus side, syncing with the phone and the computer still works mostly flawlessly, though sometimes I cannot sync to the computer because apparently, the Fitbit dongle doesn't always get detected by the computer again when it wakes up from sleep mode. The Fitbit Connect software will tell me the dongle cannot be found. This generally won't correct itself until I reboot the computer. For the accuracy issues, I am taking away a star from my rating and giving it 3 stars. ***Original Review*** The reason for writing this was to give an idea of the accuracy of the Fitbit Flex. I took my first walk this morning wearing the Flex. For comparison, I also wore an old style digital pedometer and I also had the Nike + app running on my phone. Here are the results after a little more then 3 mile walk. Nike+ 3.41 miles. 428 calories New Balance Via Active pedometer 3.37 miles. 1346 calories 7677 steps Fitbit Flex band 3.43 miles 1378 calories 7527 steps Overall, not too bad. Considering the Nike+ app is using Gps to calculate distance but the other two devices are just using motion sensors, all the results are fairly close. The reason the calorie count for the Nike is so much lower is that it's only showing calories for the amount of distance traveled. The Fitbit and the pedometer are, I believe, giving what they consider a Total calorie count the body has burned so far in the day since midnight, both from the walk and just by being alive. So in this case, I have to give the Fitbit Flex good marks. BUT, and there is always a but, I do think that when just going about your everyday stuff, the Flex is a little too sensitive. I remember the average step count the old Fitbit Ultra used to give me after a day of work and the Fitbit Flex is consistantly 1000 steps or more higher for a day. I have also tested it myself, downloading the data now, and then downloading again say 15 to 30 minutes later when I have just been sitting at the computer or after just moving the steering wheel while driving. And sure enough, the step count will have gone up some. I am sure it's picking up just the random motion of the arm while typing, moving the mouse around or just doing other random stuff and counting it as steps. Fitbit even says on its website that: "Flex is a motion sensor on your wrist. There are many instances where your hands may be moving, but your body may not be, such as playing the drums, cooking, or even burping a baby. Flex may count some extra steps here and there to give you credit when it thinks you are active." So if you need something that's dead on accurate for a whole day of activity, this may not be the best thing for it. But for actually walking/running, the Fitbit Flex seems to have done a pretty good job. Additionally, I find the Flex mostly comfortable to wear and you forget it's there. I currently wear the Flex on my dominant hand because I have a watch on the non-dominant hand. Fitbit does suggest wearing the band on the non-dominant hand. Maybe once I get the XL band, I can wear the Flex next to my watch on the other arm (it won't fit higher on that arm now) and the accuracy might improve. I have the Fitbit Connect software on my computer and have the Fitbit app on my Galaxy S3 phone. Syncing works flawlessly with both of them.

I've been using my Fitbit Flex for 6 months now, and have been very satisfied with it. I bought it solely as a pedometer, but quickly grew to appreciate the accompanying Fitbit app. My Fitbit tracks how many calories I burn each day, and I use the app on my smart phone to track what I've eaten. (The app is worthy of its own review, but the succinct version is that it is very easy to use- I can look up foods by brand or enter my own recipe's nutritional information without much effort. I can also track other types of exercise and count those burnt calories.) By setting a goal on my app (I chose a 500 calorie deficit each day) and being diligent about recording my food intake, I've lost 17 pounds in 6 months without stressing about it. I knew I needed to take action to get fit after having 2 kids and a series of stressful events had led me to significant weight gain, but I really didn't want to go on a "diet." I don't feel like I'm on a diet- the app program is very similar to Weight Watchers: it just counts calories- and I don't feel like I'm on a fitness regimen, but I'm starting to feel better about myself, and people have started to notice. There are nights that I find myself pacing around my living room to get 700 more steps and meet my daily goal- it's always a fun surprise when the bracelet vibrates and lights up for several seconds to congratulate me. I chose the Flex because I liked the sleep tracking function- as a mom of 2 young kids, I am ALWAYS tired. It may seem silly, but seeing empirical evidence that I wake up an average of 16 times a night (yes, really) encouraged my husband to get up with the baby more often. The Charge came out shortly after I got my Fitbit, but I would not have chosen that over my Flex. The Flex is only about half an inch wide, and I don't really notice it on my arm (I wear it 24/7, even in the shower.) I find the Charge to be too bulky. I have to charge my flex every 4 or 5 days. I have 2 chargers for it- one to use if I happen to be sitting at my computer for a while, and the other in my car- that way I don't miss tracking any steps while I charge it. I'd say it takes about 30-45 minutes to charge fully if I wait until I get the e-mail saying my battery is low. (Can we just reflect for a moment on the fact that my bracelet sends me an e-mail saying it needs to be charged?) The Fitbit bands are comfortable, are easy to put on, and stay on throughout my daily activity. They are, however, quite expensive. I found a 12 pack of off brand bands in various colors and often wear those, though I will say that they come off my wrist a few times a week, often when I'm doing something like moving laundry. Not a big deal, unless you don't notice it's fallen off and you lose your Fitbit. I'd recommend this product if you're looking to ease into a healthier lifestyle. I knew I needed to head in that direction, and this was an easy, non-threatening way to start.

About me: Chunky, not a fitness geek, just trying to get motivated and 'just get out there' and this is really going well. This is my 2nd fitbit device; I've upgraded from the fitbit one, and the boyfriend will inherit it next week. Reason for upgrade - I kept losing the Fitbit One in the laundry, so I wanted to try the bracelet so that I'd not forget to wear it before spontaneous urges to go walking or do errands. One the 3rd Day, I plugged the device in to "top off" the charge. I'm not sure what the charge value requirements are but I think I had it plugged into a legacy USB 1.0 hub, it appeared to charge but wouldn't wake up when I removed it from the device, and would only sync while attached to USB. After a SUNDAY email to fitbit, I got a reply back from Support Analyst 'Ana B' that very evening (!!!) about the reset process that involved the charging dongle. Upon reset, it lit right up, and it occurred to me I may have charged it from a legacy USB hub. I plugged into a known good USB 2.0 port and gave it a few hours and its back to it's full glory. (It probably didn't need that long.) Ana B. at Fitbit support, you're wonderful! What I like most about it: Syncs with Android Bluetooth 4.0 devices wirelessly, and needs NO PC setup unless you want it. My household PCs are all linux, and I hate being told to use windows for something that should be 100% percent wireless. THIS FITS THE BILL! Does the sleep logging; I work 3rds and am night owl so keeping on top of my sleep is vital, and the android scheduling tool handles my weird sleep schedule perfectly. Software app: Very robust, great food catalogue that you can modify as needed, this is a huge bonus for my particular goal and is low-carb friendly in the sense that it gives pretty accurate counts and listings. Wristband - 2 bands in your color choice come with the flex, a larger size for guys and a smaller one for women. I wear the wrist band upside down, and it looks very subtle, like any other livestrong - style wristband. Even right side up on my wrist it's very unobstrusive and not bulky. Durability, So far I've gotten it submerged in water 3 times while gardening, so issues. Things to be aware of - -- Bracelet Fastener is small and could be lost, keep track of it -- tracker itself if you get "black" is small and potentially hard to find if you remove from wristband, keep it with its charger if you need to clean the wristband separately for any reason. - If you are an Android 'Custom Rom user', confirm your ROM has enabled Bluetooth 4 if your device supports it, this was once an issue for me on my previous device. I can happily endorse this the Flex as it makes getting out to exercise much easier to track and not have to worry, "Where did I leave my pedometer THIS time?"

I've had my Fitbit Flex for about a week. At first, I was fairly impressed when I actually counted my steps and compared it to the Fitbit calculations. However, it can be very quirky and inaccurate under certain circumstances. I have mine on my right wrist, and I am right-handed, so I made sure to set it to the "Dominant" wrist setting. But, to get truly accurate readings, your arm really needs to be at your side. If I'm carrying things around the house, I don't get an accurate count. If I'm walking through the store, pushing a grocery cart, I don't get an accurate count. It seriously under counts my steps. I'd like to send it back and exchange it for the Fitbit One, which I have since heard is more accurate. However, I didn't realize that Amazon only takes returns on unopened items, and otherwise charges a restocking fee. And, I'm not sure this is defective. I think it's just not accurate. Should have bought this from a Brick & Mortar store. Edited 4/1/2014...Ok, I've been using my Fitbit for a few more days. Today I was out for several hours and my step count was still really low as, described previously, I don't walk with my hands down at my side. I'm usually busy doing other things. I had contacted Fitbit regarding the problem, but the only thing they could say was that it compared to other wrist-trackers on the market....which isn't saying a lot. I'd really like to return or exchange this thing, but can't. When I got home this afternoon, and saw that my step count was again very low, I decided to try taking the Flex unit out of the wrist band and I put it in my pocket. So far, that seems to give me a better step count. Not sure how it will work that way with the other functions. But, frankly, after using the Flex for over a week, I'm not confident in the accuracy of the other functions and will probably never use them. There is an Omron brand clip-on that gets rave reviews. Check that one out before you decide to buy the Flex. Edited 4/3/2014...I pursued my issues with Fitbit customer service, and this is what they said: " Flex will count your steps when you're walking with your arms stationary, as we do want to give you credit for this activity. This includes walking while pushing a stroller or shopping cart, or holding on to a treadmill. However, because your hands are not moving, your step count may be a bit lower during this activity." So, they have finally admitted the count is not accurate unless your arms are down at your side. I do dispute the fact that it is a "bit lower." My steps are hardly being counted at all, unless my arm is down at my side. So, for this reason, I have now lowered my rating to two stars. I did contact Amazon customer service and explained what was going on. They are allowing me to return it, without restocking charges, because it is not working as intended. THANKS AMAZON!!!

Great value for money! you can synchronize it with any phone(apple, windows and android). readings are quite accurate and price is not too bad. If you are a beginner to workout then this one is way better than the other options out there. otherwise go for garmin vivosmart.

Nice product. Tracks everything. Wakes me up without disturbing my wife

I've been using my Fitbit (and the website program) for over two weeks now. It's not a ton of time, but I have to say that I am absolutely in love! While I had a bit of difficulty figuring out the ins and outs of the product (there's no user-manual in the package; you have to go to the website and click through the product to learn about how to go to Sleep Mode, how to charge, how to install, etc), once I did figure it all out it's been a breeze and surprisingly motivating. Just the fact that it's on my wrist reminds me (and encourages me) to get moving; I find I WANT to hit my 10,000 step goal, I'm DRIVEN to get there no matter how tired I might be, not to mention that the website is fantastic for tracking your calorie-intake and -outtake to really get a concrete understanding of your success in your weight-loss regiment. I love that the website charts my daily stats, from steps and distance to weight and progress towards my goal, and I have been religiously tracking myself, feeling great pride when I'm told I've reached my goal :D The Fitbit Flex also has a sleep mode. Before I bought it, a friend of mine told me it would wake me up before my next REM state so that I wouldn't wake up groggy. Fibit does not say this simply because it's not true; it was a misrepresentation by my friend. BUT! The Fitbit does track how long it takes to fall asleep and how many times you 'wake up' (or move about) during the night, and it gives you a 'sleep efficiency' percentage that is actually really helpful. I've been enjoying this feature more than I expected because it's showing me that my sleep efficiency is TERRIBLE!!! 55% on a good day! AH! But it makes sense to me because I'm always tired and usually need to be in bed for 10+ hours to feel rested... no wonder, considering an 8-hour sleep only gets me around 4 hours of ACTUAL sleep! So, now that I know this (thanks Fitbit! ^.^), I've been taking steps to try to get better sleep: no computer before bed, watching what I eat (no chocolate or caffeinated tea), etc. It's still early, but I'll continue to use Fitbit to see if it's working and compare to my past nights' sleeps :) A final thing I want to talk about it the Customer Service at Fitbit. In a word, it's WONDERFUL! For my experience, I bought the tangerine coloured Fitbit (I LOVE colour!) and simply adored the brightness of it! Until a week in when the orange started to turn black.... It's not a fault of the Fitbit, I know it was/is something of mine that the Fitbit is rubbing against when I wear it that is rubbing off onto the Fitbit and staining it (though for the life of me I can't figure out what! My coat? Sweater? Sweat pants? Jeans? Furniture???? What is it!!?!?). The pretty orange wristband is now completely black on the edges... it's OK for casual wear, but if I want to wear something nice and keep my Fitbit on, it just looks shabby, and it made me really sad :( So, I contacted Fitbit Customer Service. I sent an email with a picture showing the discolouration and explaining that my tracker was in perfect shape but that the discolouration of the orange wristband made me not even want to wear it anymore because it just looks aweful. Within two days, I received a message from Fitbit Customer Service saying they would be happy to replace my orange wristband with a black one instead (no discolouring! YAY!!!!). I have to say, I am THRILLED with their response! Not only with the speed and efficiency of it, but with the fact that they were so understanding, friendly, and respectful of me. The only questions they asked were my name and address so they could send the replacement, no suspicion or berating questions, and as a customer I super appreciate that :) There seem to be less and less companies with great Customer Service, but Fitbit is definitely one that has fantastic Customer Service :) I feel confident and comfortable buying from them and recommending the products now that I know that they truly put their customers first. Anyway, that's my experience with Fitbit. I absolutely recommend this product, specifically this company rather than another version of the same product (I know there are lots out there... Fitbit just outshines them imo). Hope this review is helpful! :)

This is a hoax! Just received my fitbit and its unauthorized so therefor wont connect to the app. Called fitbit to have help setting it up and they said its useless that it wont work! Dont waste your money folks this deal is a scam!!!!

Muy buena para ser tan sencilla
