Very good! The only problem for me is that sometimes the corner caps fall off, idk if it's just my case but apart from that this cube is excellent.

Awesome 3x3x3 speed cube!. Super fast and smooth!. No problems with corner cutting whatsoever. It tends to always be out of the cubic shape and some people do not like it that much including myself but it is very very good!. Like it!. J2018
