The instructions are very clear and the wooden pieces are solid. It makes me feel this is a sturdy product. Given what it is, I don't feel like I'm going to break it. It's a lot of fun to put together. It's going to look great in my entertainment room.

Great product everything fit like it supposed to everything worked like it’s supposed to my kids love it. Awesome experience building it highly recommend.

Have not finished it yet, but looks great, some pieces with many joints hard to align, but no real problems, seem a little smaller than I imagined.

This piano puzzle was excellent and went together well. It operates well, and will make a great birthday present for my wife. The only drawback was the missing wax that is absolutely necessary for all of the interacting gears to operate properly.
