This puzzle's review is in terms of shape-mods, and not a comparison of a speedcube. In shape-mod terms, this isn't a speedcube shape mod, but corner cutting is pretty good, with 45 deg. on some faces, and the turning is overall fast. locking is not a problem, since you probably won't be turning that fast. Since I have it on loose tensions, corner twisting and popping sometimes happen. This can sometimes be frustrating, because your fingers can't grip the cube well when you try to do some moves fast.
