Out of the box it is smooth and fast, but definitely too loose. After lubing the core with traxxas 50k and the rest with DNM-37, and tightening the cube, it performs vastly better than the cubic aofu GT. It is one of the best feeling cubes I have tried, being extremely quiet for a 7x7. It has a similar feel to the yuxin red but it is definitely faster. The color shades are excellent, and it corner cuts very well. My only complaint is that the center piece caps do randomly fall off, while the edge and corner caps are glued on. If it were possible to magnetize this cube, it would probably be the best on the market, but as it is impossible to add magnets to this cube, I will give the slight edge to the qiyi wuji. There is just an incredible difference in performance of big cubes with and without magnets, as layers often misalign, which is unfortunate for this cube. Other than that, the cube performs well and is a joy to solve.
