I bought this cube because of a trip I have coming up where I can not keep a full sized cube on me at all times. I didn't think it would be that good, but the only thing I really cared about was that it was small. When I got it, I did not expect it to turn as well as it did. It is very crisp and fast. Its regular corner cutting is decent, but it has no reverse. Both corner cutting and speed improved when I tensioned and lubed the puzzle. The only things I found wrong with the cube is that the non-existent reverse corner cutting leads to a lot of small lockups, and the corners and edges of the cube feel very sharp, meaning you can only use it for a short time before your hands start to hurt. Aside from that, it is a great cube for its size!
