It's fast and smooth but it does catch quite a bit. Comes lubed and ready to go. The matte finish feels great in the hands. Springs are easily adjustable by hand (unlike MoYu's dual adjustment system). Compared to the MoYu Super RS3M (non-maglev), this is much smoother, lighter, quieter, and faster. It does require getting used to but this is a very comfortable cube.
This is a quality speedcube and I would recommend this for people who are wanting to step up from beginner/budget cubes.
