The MoYu AoSu GTS M 4x4 is one of MoYu's most competition-ready offerings with the implementation of magnetized mechanisms right out of the box to improve tactile feedback and outstandingly controllable turning speed. This speedcube also features a revamped anti-lock-up design that was prominent in the first first version, in addition to its incredible corner-cutting abilities. Used by many as their 4x4 main, this is a premium option for your speedcubing endeavors and aspirations.
