The MoYu AoShi WRM is a new 6x6x6 from MoYu, it is 2mm smaller than the MGC making it the smallest major 6x6x6 release, continuing the trend of big cubes reducing in size. The AoShi WRM is probably slightly better than the MGC and continues in the trend of feeling of the other cubes in the WRM series, it is quite fast but also retains stability, it is not quite as fast as the MGC but does not have the stability issues and I don't think I can recall it popping on me so far! You can buy it here
