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 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.

This cube turns extremely well, and it is so hard i cannot even make the centers! I really recommend this puzzle even tho the prize is high, its is really worth it!
