SengSo YuFeng Megaminx (Magnetic, Ball-Core)

The puzzle is pretty good but some of the pieces need to be snapped back into place from time to time, I'm not sure if it's a fault with the puzzle in general though because it isn't packaged very securely (it just rattles inside the box with no plastic to secure it) and my delivery driver very kindly threw it over my garden fence onto the concrete path.
