The puzzle doesn’t work great when it arrives, but I expected that. The puzzle needs to be disassembled, and the extra plastic needs to be filed or sanded from every piece.

After all that, the puzzle moves perfectly. Very fun.

when the puzzle came it moved good but really loos, it explode and affter assmbling (that took some time) and lube it in the time I assambled the puzzle, it moves perfectly.
