Bought for son. Loved it.

It is a very good puzzle, I bought it for my son to play with. Its much harder than it looks; my son had a few temper tantrums doing it. Good quality and metal (zinc alloy). One star off for disturbing fumes it leaves. The metal smells like well...a metal smell! The smell is really strong though.
