Review: Coolest cubes ever! - Got these as a fidget for my son so he'd having something to do after conquering the classic rubik's cube. They're high quality and move smoothly. They have a nice weight to them, so they don't feel cheap. They're challenging but not impossible. I like the metallic rectangle one the best.
Review: Cube set - The cubes in this set were significantly smaller than expected but that hasn’t deterred kids or their parents from working to solve them. Have held up so far. For the mind use while having fun, these were a good value.

### ⭐⭐⭐⭐⭐ Coolest cubes ever!
*by C***R on July 20, 2023*

Got these as a fidget for my son so he'd having something to do after conquering the classic rubik's cube. They're high quality and move smoothly. They have a nice weight to them, so they don't feel cheap. They're challenging but not impossible. I like the metallic rectangle one the best.

### ⭐⭐⭐⭐⭐ Cube set

The cubes in this set were significantly smaller than expected but that hasn’t deterred kids or their parents from working to solve them. Have held up so far. For the mind use while having fun, these were a good value.

### ⭐⭐⭐⭐ Interesting twist on the Rubrick's cube!
*by B***E on April 11, 2016*

If you're looking for something a little different from the "normal" Rubick's cube, you'll want to check out the YJ Cube Set. (Why they didn't come up with a better name for these, I don't know, but I'm not here to judge the toy, just to review the product.) These are really funky (including Fluctuation Angle, Wheel, Mirror, 3x3 Square King Puzzle Cubes), which, in my opinion, actually adds to the fun of this toy. As long as you find the lines on these toys, they were easy to turn and maneuver. You'll need to be gentle with these because you can accidentally take the corner pieces off. All things considered, though, you'll have hours and hours of fun trying to put these back together again. Of course, some people will find these more irritating than fun, but only you can decide this. I received this product in exchange for my honest opinion, which you've read here.
