The MoYu Aosu GTS2M was MoYu's second attempt at making a good magnetic 4x4x4 and is probably the best 4x4x4 on the market for those with large hands, since it is bigger than the other 2 most popular 4x4x4s among top speedcubers, it is stable and fast and used by some of the best 4x4 cubers today and is highly recommended in the cubing community.
