LanLan Gear 3x3 Hexagonal Dipyramid

poor quality

Interesting puzzle but poor quality. My son solved it once just fine, the second time he went to scramble it the top popped right off. Because of the type of puzzle, it couldn't be popped back in place. It looked like a tiny screw was the only thing holding it in place. If you are into gear type puzzles you may want to choose a different shape.
