MoYu AoSu WR M 4x4 Magnetic is MoYu's 2019 flagship featuring some key features. Some of our favorites are the new compact size, upgraded positioning system, new half-bright stickerless shades (Stickerless model only) and moderate strength magnets. The performance of the AoSu WR M is unbelievable. Silky smooth turning and a high corner cutting tolerance combined with a compact, stable core make for a truly amazing solving experience. The addition of factory-installed magnets adds to the stability and control that the AoSu WR M offers.
