The GAN 251 M is the newest 2x2 speed cube from GAN. This cube features all of the same characteristics of the 249 V2 M like great corner cutting, matte finish, a light/airy feel, and a medium magnetic strength. This small increase in size (2mm), although seemingly insignificant, is definitely noticeable and gives the solver much more control over the puzzle and ultimately leads to a better solving experience!
