This cube turn really well, add some lub and this is almost a speed cube (that's the only reason I give it 2 stars). The down side on it is that, first, the pieces are to far from each other so you can't attach other bigger lego pieces between the gaps. So I don't understand why the lego pieces that came with it are not flat tiles. Also, I don't know if it's me but once that I put the lego "stickers" on the cube, they became IMPOSSIBLE to disasemble, even with some special lego tools. So I can't really play with it, like (I think) it was suposed to be. This cube was a good idea on paper though.
