It gave me a real challenge. It's really fun to work with and fun to amaze friends by letting them undo it and then solve it. Instead of the usual colored Rubik's cube, you figure out the places of the shapes. It is really something unique to work with, and it kept me busy for hours at a time. If you like puzzles, you will love the ShengShou Mirror puzzle cube.
It's almost unbelievable how much better this puzzle is than Rubiks' original brand. Super smooth turning, the ShengShou springs system really shines here. It comes lightly lubricated. Good quality stickers, they're like polished aluminum, and you see the grain or strains in them, so you can treat this like a super cube, that is, you can orient the centers, that strains give an alignment to the center cubies.
