Bits and Pieces EZ Atom Metal Puzzle Marble in The Center Brainteaser Puzzle - Metal - Remove The Marble Brain Teaser

This is a great puzzle, make sure u pay attention to how u take it apart or you will have trouble..lol. it's a great puzzle for all ages!

I bought this for my boss, who loves these types of puzzles. He thoroughly enjoyed it, and said he found it to be great quality. Personally, I found the design quite interesting. I would definitely buy this brand of puzzles again. Highly recommend! Oh, and for those who are wondering what level of difficulty it is in comparison to similar metal puzzles - I would rate it at Level 3.

Overall, this is a nice puzzle. I like it's simplicity, however a flaw in it's design detracts from it's artistic presentation. When the puzzle is assembled, the tolerance isn't tight enough for it to hold it's Atom structures shape. It's my opinion that the golden piece with the catch is far too wide. The tolerance on the rest of the puzzle is fine. It's only that notch on the golden piece is much larger than it needs to be. As a result, the puzzle will always feel loose when assembled and therefore detract from it's ability to be a beautiful piece of art.I call this a flaw in it's design because there's no reason why the the notch on the golden piece is double the width that it needs to be. It should be cut to the same width as the notches used on the rest of the puzzle. Also, there's no reason why the notch on the golden piece is cut on both sides. That too adds to the loose instability of the puzzle when assembled. A simpler cut for the notch/catch on the golden piece would greatly improve the puzzle in my opinion.Overall, this is a nice puzzle. Better than expected. It's built very solid.

I'm happy

I was kind of let down. I'm used to Hanayama puzzles I guess. The fun is usually about both how to disassemble them and then to reassemble them. This seems like it's missing a step. I bought it because it looked cool together. To open the box and see all the pieces lying there was disappointing. However, the included solution was only how to put it together, so I'm assuming that is the way it is supposed to be. The problem is that they are just loose in the box. No foam protecting the pieces from being tossed around during shipping. The blue marble looked like it took a beating. Once together, it's very loose fitting and falls apart quite easily. Trying to find a position in which it could be set down to be displayed was a challenge in itself. Personally, I would not give this as a gift. I'll stick with Hanayama from now one.

Excellent puzzle

Very good product, for my son is taking physics to be a theoretical physicist. It keeps him entertained.

I've had this little puzzle for a long time. I'ts been sitting on my desk and I pick it up now and then and could never get it apart. I even though through the reverse process to put the puzzle together from 4 separate pieces and actually had the right idea (now that I know the answer).But when I tried to do the reverse of the assembly process, I couldn't get the puzzle to budge. After reading another review that some burrs were preventing movement, I looked up the solution, and it turns out I was right!I had to force the first step of the solution with a significant amount of force to get it to come apart the first time. But now that I've gotten it apart the first time, it practically falls apart on its own without even knowing the right solution.Overall, pretty disappointing.
