Out of the box this megaminx blew me away by how smooth and fast the turning was.it was also very loose out of the box. but I have heard that it's uncontrollably fast. the rigdes on this megaminx are only on the outer side. The stickerless shades are very nice. The magnets in it are a bit on the stronger side and the magnetic bump is also satisfying. But I have experienced some corner twist which is kind of annoying and have slowed down my times but it's not that of a big issue and it has to me sometimes. This megaminx is very good at preventing pops and at corner cutting. It could corner cut about 45 or 36megaminx regular corner cut and about line to line reverse corner cut. So this megaminx is really good and yeah it's my main.
