about it : rubiks diy is produced by http:/www.rubiks.com company
what's the difference : if you ordered a rubiks cube diy it will be not assembled so that's better
to tune your cube well as you like unlike the normal rubiks cube .

any cube is better ?? the answer is the diy cube sure (do it your self )
i really prefer diy cubes it's simply amazing it's like a dream :) .
