As I already have the Megaminx, I thought that even without the centers should have a little more difficulty. And actually, I still have not managed to solve it entirely, but in an hour, I managed to make a deal and the first floor. So the logic of things, I should not delay or block the finish! In any case, it is handy, it runs well and is quite durable.
NB: In hand, it is a little bit bigger than the Megaminx.
