... is it a ball mech like the Rubiks 4x4x4 and the pieces roll over the ball?
Well, there is a ball inside, and the ball has grooves. Unlike the 4x4x4, this ball is split in two for the main rotation.
still an awesome little puzzle i want one :p
What would refrain you from just buying it? It cannot be its low price.
it has some of the looseness issues
Not too bad with this one, it turns very well.
