As expected, this cube was amazing out of the box. Corner cutting was excellent and it was very smooth both on the inner and outer layers of this cube.

This is an amazing 4x4. Out of the box, great turning speed and corner cutting. 3x3 part of the solve exceptionally smooth. No pops or locks yet. Love this cube!

Qiyi is an AMAZING company!! And that amazing has been put into this 4x4 cube, this is a very impressive cube, this cube excels other 4x4's in all aspects. Well done to You Qiyi and thank you CubeZZ for selling this wonderful cube. GO buy this cube guys, you wont regret this decision. :)

But in my opinion this is worth it for the price, but if you are looking for something cheaper and GREAT, get the Yumo Cangfang, also known as the Kungfu Cangfang. Have a great day guys
