this cube was hyped up by many people, especially my friends. one of my friends got this puzzle, i tried it out at a comp and it was amazing so i got one for myself. i was super excited to unbox the cube when i was with my friend and when i turned my cube for the first time, it felt REALLY BAD. i was really shocked as to how it felt - it was EXTREMELY slow and gunky. my friend said that when he got this cube that it was controllable and a bit slow but no where near as slow as mine. heaps of lube and dozens of solves to break in the cube and its lube has improved the puzzle, but still very slow.
im still maining it over my much faster aochuang v6 single track as speed doesnt matter too much on 5x5 as you need a slower cube for look-ahead but do consider all of this before buying it.
as i have already said, my friend said that his felt MUCH better out of the box than mine, so maybe i just got unlucky or something like that, im not really sure.
