## Customer Reviews

### ⭐⭐⭐⭐⭐ Good "Gift"
*by N***. on February 21, 2026*

Bought these to torment a smart coworker. It worked.

### ⭐⭐⭐⭐⭐ 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.

### ⭐⭐⭐⭐ These were a lot of fun to figure out
*by H***N on October 4, 2016*

For the price you can't beat this. These are 4 shape mods to the regular 3x3 cube, meaning you solve them similar to how you solve a regular 3x3. These were a lot of fun to figure out, especially the axis cube or angle fluctuation cube how it is listed here, that one I found to be the most challenging. My only issue is that on two of the cubes a few of the center pieces face plates tended to fall off very easy, I had to put a small dab of superglue to keep them from falling off with every turn. Other than that minor issue these cubes turn well and are fun to solve. I would recommend them to anyone looking for a challenge after completing a 3x3.
