I needed a new cube since my tornado v3 had a magnet pop out, so I got this cube. The UV coating gives it a good grip to it, and it is VERY FAST right out of the box. Lubricant will make it better, but it is still good for out of the box. The turns do not sound smooth, and that doesn't matter to me. It's more speed than smoothness. There is only one problem for me and that is the tensioning system. I still haven't managed to get the center piece of for adjusting because I'm afraid I might break it.
Awesome cube.
