Review: Excellent puzzle for advanced puzzlers - This puzzle is very sturdy and well designed. The instructions are fabulous, and as long as you have patience to sand and wax every moving piece, it will be great! Up to a certain part in the instructions, it will have you double-check that the gears are working properly. After that, everything doesn't work together until you have it totally together, so I wasn't sure if I was putting it together right. But after I finally assembled the lid, I left the lid open (just in case I needed to take something apart), and following the unlocking instructions, everything worked great! I was VERY happy I took the extra time to sand all the rough spots and wax ALL the moving parts. Because of this, I have a very fun combination lock box that very few (if any) people will be able to figure out on their own. You can see in the picture that I stained a few of my pieces to make it a contrast color and a bit more interesting. You can do what you want, just be careful to either dry the paint/stain, or make sure they are not part of a moving piece, because the wood may swell. This lock box is by far, my favorite puzzle to date, and I have put together many of these 3D wooden puzzles. I love most of them, and love that most have great directions. Wood Trick's instructions are wonderful, and it's very rewarding to get something like this put together. I highly recommend this puzzle, not only is it highly quality and has thick wood pieces, it's VERY fun, and VERY rewarding to complete.
Review: Buy this puzzle! My favorite so far! - Amazing puzzle! I thoroughly enjoyed this puzzle and it was well worth the money. The finished product is really cool to look at and show others how it opens. A few things I would suggest before taking on this puzzle: 1. Invest in some parafin wax, a wax melter and a small paint brush. It is far easier to brush the wax on than to try to rub it on with that little piece of wax. You will need a lot more wax than provided anyway. Only wax the pieces that it tells you to and where on the piece it says. 2. I found that a rough nail buffer was excellent to sand the pieces that needed sanding. 3. Buy a small craft hammer. Trust me, it will save your fingers. They get very sore putting the pieces together. 4. Use the tool to push the pieces out. It is found on board 6 and is very helpful. 7. Pay close attention to the direction of the pieces. It’s very important to get pieces a certain way. Always pay attention to the exclamation marks. They are important. 8. When waxing pieces, apply wax and then burnish with your thumb and finger. Remove all wax from the face of the piece with your thumb nail. Do not over-wax! Wax becomes like glue when too much is used. You might try a wood lubricant instead. I’ve just recently found that product and am going to try it on future puzzles. 9. Take your time and enjoy the puzzle. Dont try to rush through or it won't work in the end. Make sure that each section's parts move like they are supposed to before moving on. All in all, this is a great puzzle. It is very well make and the instructions couldn't be more clear. It is well designed and a lot of fun to put together. It took me about 7 hours to complete and it works perfectly....as long as I follow the instructions. I am still working on remembering all of the steps to open! Have fun!

It was easy to put together the latch doesn’t really work but I didn’t wax every single item so it might have been that
