There is not doubt that the WuQue is the 4x4 to get. Out of the box it is a little sluggish, however after breaking in the cube and lubrication it begins to go away. It has a unique feeling, where the outer layers are sticky to prevent misalignment, whereas the inner layers are very smooth. The corner-cutting on this cube is excellent, along with high quality shades. The cube is very stable and quite fast after breaking in the cube. If your in need of a new 4x4, the QiYi WuQue is the one the get. However, even for new cubers looking into 4x4, this is still the best choice as well!
