I got this cube over a year ago now because I like how it looked. Although it's a shape mod, no matter how many times I solve it it's still challenging every time. The turning is great but the sticker quality isn't that good.

The Moyu 4x4 Windmill Cube is great for a fun and a challenging solve experience. The stock stickers are great and I have had no problems with them. The small corner stickers have a chance to fall off so be careful. The turning is good (just like the Aosu mechanism). The solving is difficult due to the centers and parity. I would definitely recommend getting this puzzle if you are into non WCA puzzles.

Just like the aosu windmill cube , this cube is really hard and turns extremely well. If you wanna get into shaped cubes, this is an excellent choice.
