YJ Cube Set - 4-Pack, Includes 3x3 Fluctuation Angle & Mirror Puzzles, 2x3 Wheel & Square King Cubes

got these for a friend. they are driving him nuts. exactly what I wanted.

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.

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.

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.

My 5 year old son loves them all! They are great fidgets for him that work his mind!

My boyfriend is the kind of person who likes to exercise his brain and prefers work to having fun, this was the PERFECT gift for someone like him! I gave them to him as a christmas present and about a month later and he has only solved one! He is super smart and a mechanical engineering major, but he will spend so much time playing with these and trying to calculate where the next one goes. They did come solved so i had to mess them up before he got to them, but otherwise it’s been an absolutely amazing gift! Highly recommend for anyone looking to gift a math nerd

These cubes are going to be a stocking stuffer this Christmas, but they look just like the pictures and are very colorful and fun looking.

The kids gagged when they saw them! Yas hunny!
