This cube is good after breaking in but is scratchy if you like that. DO NOT DROP THIS CUBE the red and white center pieces snapped on mine I was devestated because it was my first 4x4x4. So use it over carpet or table not standing up on tile. All in all a good cube but I'm not entirely satisfied with a bunch of pieces in a plastic bag.

The QJ 4x4 is safe to say that it is only better than the Rubik's brand. This cube uses that mechanism; but, it performs better than a normal Rubik's brand. Stickers are dull out of the box, corner cutting is terrible, only the inner layers are smooth, and the performance is bad overall. I would not recommend this cube.
