Really good puzzle, in my opinion: definitely better than the Valk without setup. Turning is similar to the WRM 4x4 and the MGC 6x6 from my experience and is generally stable. I’ve only had 2 pops on it so far (having had it for a month) and the lockup’s are easy to fix. The speed may be a bit too fast out of the box for most people. Overall - solid cube!
