If you are thinking about buying this, just get the Shengshou one, it will turn so much better and be less expensive. With this puzzle, I was disappointed with it out of the box. The "flower petal" center pieces catch and pop off all over the place. So I used scissors and cut them from being a "U" shape, to a "V" shape (if you look at those pieces from the back, the plastic is thick where the "V" is, and there are "wing" like protrusions that I just cut off. The pic is how they look after the mod). This makes it so they don't catch or pop. If you care about the looks of the puzzle though, you might want to do this a different way, in order to get smooth, clean cuts. Next I pulled a piece or two out so that I could lube the puzzle, and after all of this it was SOO much better! Still not "speed cubable" or anything but usable for sure. If you have one already, that's how you can make it good, otherwise, just get the Shengshou one.
