Same as the first ROKR puzzle I did, packaged well and all the pieces were easy to pop out and assemble. Once concern with the way one piece is built with 3 little wood screws that go into opposite sides staying put, but once the built piece was snapped to the main board, it worked flawlessly. The arm that works the elevator is pretty cool to watch -- I've had 2 of these this Christmas and will consider getting a 3rd in another month or so -- great fun to assemble and end product is a neat showpiece! Highly Recommended!!!
