ROBOTIME 3D Wooden Puzzles for Adults, Treasure Box 3D Puzzle Mechanical Ring Box, Gift Choice Hobbies for Brain Teasers Enthusiasts

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!

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!

The media could not be loaded. Bought this for a dual fold purpose. 1. Needed something to occupy my mind for a few hours during quarantine 2. Creative idea for a gift box. Hit both on the head. I enjoy putting things together and figured this would be something nice to do and have a practical use when it was complete. I liked it enough to look into other things that I could put together by the same company. I like the construction and the wood feel of the pieces. I only have a few negative things to say but nothing that really draws from the product. 1. The wax that comes with the kit. That you are supposed to use to lube in between the moving parts must of melted and solidified in storage because it was not easy to work with. 2. After completion I noticed that the locking mechanism was easy to work around simply by twisting the top of the box. Not a totally killer but does take some fun out of the puzzle. Overall I’d recommend this as a gift for someone that likes building working things.

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

This one is a good one to do. I collect these and even sell some that are way bigger then this one. You Just have to be careful getting pieces out, especially A-6. If it breaks, don't panic, as that is one of just 2 xtra pieces. The rest of the 148 pieces if you break, I can't find a way to order xtra parts from the UK. I also used frog- lube, the wax form instead of their wax ( which is terrible ). It makes those wood gears roll. After it's put together, please be careful with the combination knob that turns just like an old school lock, 2 times to left and one to the right and back to the third digit in the combo code. I have had 2 front knobs break off if gears are not waxed enough and are used a lot. So i have been adding xtra glue when assembling the knob, which is a huge piece that runs the main gears. Also if you do break off the knob, don't panic..just glue it on and disable the main lock. Then it will still lift open by hand and close just fine. It becomes to much to enter the pad lock each Time one wants entry to the box. The 2 rear keys turn on separate gears, turn those opposite direction and the box opens comes up and opens its trap doors. This secret place Will hold rings and jewelry. There is also a secret compartment on top. See my pictures..I will say that the gears in this one box are amazing but just keep waxed. There are 3 different sets of gears, each accomplishing a different task. I also stained mine using a furniture stain market.

I had a great experience putting this thing together. Everything fit very well and snugly together. I did not have to use any replacement pieces for this project, except on one piece I had to use a very tiny bit of superglue just to make sure it did not move. I see all these bad reviews for this project and all I have to say to that is if you're not good with your hands or "engineer like", of course you're gonna have problems with putting it together. It isn't a lego, you need to be able to adapt to unexpected circumstances and make it work. These people just whine that it's a bad product but they just suck at this type of stuff, go back to legos you whiney child. I would say this project is definitely 17+ and not for kids. Kids are likely to break it and need to stick to the legos.

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.
