ROBOTIME 3D Wooden Treasure Box Puzzle Unique Model Kits to Build Mechanical Engineering Kits Great Birthday for Adults and Children Age 14+

Overall a cool and fun puzzle to build. There are two downsides imo. 1. When you're almost done and building the lid there are two pieces that wrap around it then you have to push them into a tight slot. This is when you can break this piece very easily so be careful. They give extra pieces for some stuff but all of them are not really breakable. I wish they gave one for that lid piece. 2. You get toothpick looking piece that connect much of the puzzle, you need a knife to cut these, kind of annoying. They do give you plenty incase you screw up though. Other than that, it was exactly as expected and turned out great!

I bought this as a birthday present for my grandson & said he wants to do it with me when we’re no longer lockeddown so it may be a while but it looks great & we can’t wait.

Not an easy puzzle to open if you dont know the secret. great for kids

Beautifully cut wood that fits together well considering it is wood. Yet, some of the gears are very easy to break if not approached carefully. Be liberal about sanding down, with provided sandpaper, any parts that are hard to insert. Don't forget to use the wax provided as well. I gave it 5 stars overall because we broke some parts assembling it with my teen and they kindly provided us a replacement sheet at no charge. Still haven't figured out how all the combination mechanisms work. It would be nice to have a video showing how all its locks should work. Overall, a very nice project to spend time assembling.

This was a fun project to complete, the instructions were easy to follow and the pieces were very easy to pop out of the wood sheet. The only gripe that I have is that the pieces that are meant to bend are very easily broken, though a bit of gel super glue made an effective repair. All in all a good product, just be super careful with the bendy bits!
