The Aochuang is incredibly smooth and fast. Inner layer turns are completely effortless and allow for fast slicing (even <M,U> U-perms!). Outer layers are smooth and speedy, though I find there to be a few catches due to limitations of corner cutting. Overall this cube is a pleasure to turn, and I've yet to had any issues with pops.

awesome cube. Definitely recommend

This is a very fast, easy to turn, flexible 5x5 I would recommend to anyone looking to get into 5x5
