Review on Padlock Hanayama Metal Teaser Puzzle by Harry Tulsa

We ordered 4 of these Hanayama, Castle, Enigma, O'Gear and Marble puzzles. I'm ashamed to admit it while we've only just gotten into the O'Gear. In fact, some of our friends understood o'Gear too, but everyone is nervous about the rest. We managed to disassemble the marble but couldn't put it back together. Our genius brother-in-law, who has a top-secret military job where he basically solves puzzles to make a living (that's about all he can say about it), got riddled when he came to visit, but they until then He had to leave so we ordered more and sent them to him for his birthday! In any case, they are really cool and make artful, interesting decorations on our living room table.
