This is just a round version of the rubex cube. I got this as a gift for my 10 year old grandson. I thought it was more of a cross between a character spinner, a stress ball, and a popper, but it's not. It's a little stiff to play at first, but should loosen up as you play. Which could also be bad news in this regard. Inside is just a big yellow sponge that eventually collapses. Then you just have free colored balls rolling around in it and nothing is keeping them in the correct colored holes.
