When I heard about, qiyi's new release - the Wuwei M 3x3, I expected an okay cube, lacking some of the qualities that high end releases held. Despite this, once trying it out, the cube caught my attention instantly. It's 55.5mm size was slightly smaller than what I was used to, but I quickly adapted to it and now prefer it. The cube's shades are pretty much identical to those on the Valk line of releases, and I can't say I dislike them, and its magnets are at a pretty strong strength. The performance of the cube however, is phenomenal. With easily over 45 degree and line to line reverse corner cutting, the cube's smooth yest fast feel allows my times to improve majorly on this puzzle, so at only £13, I cannot see any reason not to buy this cube, and it instantly became my main over the GTS3 M and matches the performance of many of the top performing cubes on the market right now.
