RK ROYAL KLUDGE RKS70 Ergonomic Split Keyboard, Wireless Gaming Keyboard with Bluetooth/2.4G/Wired, 75% RGB Hot Swappable Mechanical Keyboards Fixed Wrist Rest for Win/Mac, Brown Switches Black

Update:RK contacted me and helped me with the issue, it was a faulty keyboard and they replaced it.works like magic!Ill start with that it came - Opened and scratched and usedWhich sucks and its hard to say if its amazon or the seller - but i ordered a new one as its sketchy to connect a device with a firmware to you computer and install Chinese drivers.beyond that, i never had so many missed keys, i have to retype everything multiple times and i use many different keyboards, laptops, servers cheap keyboards, mechanical keyboards.what seems to be the problem is some key presses dont register, and sometimes there's a lag or a hang when typing.the lights and all that stuff is nice but i need a keyboard i can type and not retype everything a few times.i did get the brown switches as i used these before.biggest cons:.- used- missed keysi havent got to use it in its ergo form as i was trying to get used to typing on it, but just that was tedious.ill try to reset settings but the missing keys is the most annoying of it all.i dont know what the polling rate on this but it feels slow, my Bluetooth keyboards work faster than that.also i noticed that space, backspace and enter have a of movement and sometimes they dont press even though it went all the way down.i dont know if its only this keyboard or they all do this, but it drives me crazy to be honest.noise level is ok, not too loud which is nice for a mechanical keyboard/i use it wired.

Overall a decent keyboard., I have a couple of more expensive ergo mechanical keyboards already (Cloud 9 C989 and a Kenesis Freestyle gaming keyboard) and they’re both good, but they have loud Blue keys and I wanted to swap to quieter Brown switches for my work computer. I’d used a couple of RK keyboard before and figured this would be a good bet at the price and would give me the flexibility to hot-swap in whatever switches I want.Overall, I like it. Decent weight, good key action, hot-swappable, and the feet that let you adjust tenting are nice. USB A/C/dongle/Bluetooth connections and support for 3 BT devices are appreciated.However, I bought this to use with my work MacBook Pro, and while it has a Mac mode, the F-key row on the far left is useless to Mac users. They’re pre-programmed to CTRL-C, CTRL-V, etc., and while the keyboard does have a Mac mode, flipping to that should make these keys send Command-C, Command-V, etc to match Apple’s annoying different keyboard scheme. Because CTRL-C, CTRL-V, etc don’t do anything on these keys and the keys aren’t programmable, they’re useless to Mac users.Otherwise, my only real gripe is the lack of a Function key row. This isn’t a tiny keyboard anyway, and I’d happily have had it take up a little more space to have dedicated function keys. Luckily, since I’m using it on a Mac that’s not a big deal, but that will keep me from ever switching this over to my gaming PC.3.5 stars rounded up for good build quality and flexible connectivity, but half-baked Mac support for a keyboard advertised for both Windows and Mac.

The brown switches are nice, with a thunking sound. The keyboard works fine, and the split is also alright. Overall, the solid keyboard feels flimsy when detached into the split mode.There are some reviews on the app not working or not having enough options. The options are fine for someone who doesn't need to extensively mod the keyboard. I currently do not have any issues with the battery or the overall function of the keyboard.

LOL this thing is so cool. Got that retro punchy plastic key press with clicks. Feels stupidly durable and mechanical like I’m a rad hacker. Is a bit thin when attached together, likely to make either side less big for each hand individually. It gets some getting used to and I hate that, but I have not for one second felt like it was junk or overpriced. It feels like I treated myself. The hand rest goes hard as heavy metal so make sure you get some cushions to go with. It’s DURABLE heavy duty with a nice coated protective texture to it, stark black (hand rest). The cord is also coiled to reinforce it which is nice. Love the color coating of the keys. Pretty heavy too so both sides remain rather stationary when typing which is a mega ++!

The quality is really good, but I made some modifications to the layout to make it more comfortable:The macro keys are a bit annoying and I couldn't get used to using them, I ended up disabling them, removing and remapping some other keys like "`" and "ESC".But i really recommend the keyboard.
