Out of the box, this cube is amazing. Slightly scratchy, but really fast and flexible. But after a thousand or solves, the pieces smooth out, the speed goes away even with stardust and lunar, and it becomes very weird. I won't even mention the pops from the split piece design. And for 48 dollars there are numerous other options. To give the cube some credit I did break my pb single with a 7.77. (Although I beat it recently with a 7.56 using a gan x) it also looks very pretty although that doesn't do much for the performance.
