Got this cube from cubezz.
Out of the box it was really nice, which caught me off guard. I bought it with a sticker less aolong, which was terrible out of the box (my other aolong was my main). It's smooth, fast and doesn't lock up. I can't say enough about it at this point.
It's easily my new main. I'm a mid 20s solver, so not terribly fast. I have a guanlong, sulong, yulong, aolong, zhanchi, gans 357, and hualong to compare to. After lubing the core and assembling with weight 1 on the pieces, it's great. Moderate tensions, I have no complaints. After about 50 solves it's just a pleasure to use.
Everyone knows the corner cutting, but others have called it slow, but mine is plenty fast. It's as fast or faster then my aolong with cx3 springs. The springs are totally different then my other moyu puzzles, gold color, longer, but lighter. Plus the plastic seems different, shinier?
Overall I really like it.
