I love the feel of this cube. I think I see why cubers say this is a "slow" cube, but it feels very good to turn. After a break in period of a few months and lots of solves, the cube feels just as fast as the MGC.
The construction is very solid. I haven't had any pops, but I'm sure its possible. I have the stickered version and the colors look great.
As with some of the other X-Man cubes, they have a more unique feel than say a Gan, Moyu, or MGC. But after the break in period, I would put this cube next to any of those in performance. Excellent cube and well worth a try.
