I recently bought this cube and I was really exited, because this was my first serious speedcube. I did the first few turns, which were really good, but it was a bit loose so I tried to turn up the compression. The very second I turned the dial, the maglev compression system popped apart. All the pieces came off including the center pieces and the maglev compression dials. I tried to fix it for a while, but it was no use. If it was the cube, or it was damaged in shipping, I don't know. This is something I didn't see in in any youtube videos or reviews, so I want to bring this to your attention. Do not buy the maglev version of this cube. It will break if you use the compression system. Otherwise, it had good turning. It sort of felt like a tornado V3 I tried once. If I only had $15, I would but the spring version.
