Pros: The cube is fast but controllable. Corner cutting is occasionally 45 degrees, and is half a piece most of the time. Reverse is the same, being half a piece. I also got a 9 second solve single. Cons: I sometimes will hear spring noise, which concerns me. The cube also has a more of a crunchy feel, rather than more of a crispy light feel, and that gives me the impression that it may not be a Lingpo. But overall, it is a great cube. Update 4\8\18: I was able to specify that this is a lingpo, and it is not crispy still. At that point, I was still non cuber status, so excuse my craziness.
