Review: Strikingly beautiful and rewarding to build - I bought this "hidden treasures" box for several reasons. It's beautiful to look at, is incredibly cool, and opening it is a bit of a puzzle. But what I really bought it for was as a gift to someone special in my life. Spending the time and energy to build this beautiful box (about 10 hours for me) was a pleasure, and I plan on putting a ring box (perfect size for this) on the inside and giving it to this "special person" so they can admire the box and its intricacies as they try to solve the puzzle and open it, finding the ring inside. The instructions were easy to follow. You have to be very careful popping the pieces out of the boards as some of the gear teeth came apart slightly. No real damage, but be careful. It is also worth noting that the instructions call for wax for some of the mechanical parts. I didn't know this beforehand, but it wasn't an issue for me. I went to the store and bought a long skinny candle and rubbed it along the gear teeth and other surfaces where wax was called for. Seemed to work perfectly for me! My fingers are a bit sore/raw from working with the box for so long. Some of the pieces are small and require some decent force (but not too much!) to put them into the holes they need to be in. Overall, 9/10. Another thing worth noting, it comes with a small shepherd's hook tool to aid in punching out the smaller pieces, and it also comes with some additional parts which is nice. I managed not to break any of them. This was my very first project like this. Not too difficult.
Review: Neat, precision, intricate gearwork. A sight to behold when done, but a few caveats! - Overall, this was a really great product. My 16 year old niece and I spent a few evenings putting this together, and it's really a neat little kit: nestled into this puzzle box are several reduction gears, four-bar linkages, sliding bolts, and even an iris... all made out of wood. It's really pretty intricate, and the result is a rather attractive little box as well. If done carefully, the mechanisms all work surprisingly smoothly, and all the pieces fit together quite nicely. A few caveats and recommendations for those considering assembling this: 1. This isn't a kit for younger kids. Attention to detail is important, and many of the pieces are small and delicate. I also strongly wouldn't recommend this as your first Ugears project: start with one of the simpler kits to get the basics down. 2. Lubrication is what makes the difference between a smoothly operating box, a roughly opening box, or a non-operating box. They recommend a "candle", but realistically, after a bunch of experimentation? Burt's Bees beeswax chapstick. Easy to apply, easy to clean up, and minty fresh. 3. Pro-tip: there are a lot of studs, gears, and bearing blocks that are tiny, and you have to punch out a bunch of them that are all exactly the same. Carefully score the laser cuts with an exacto first. Get a spudger to use to help out some of the smaller parts, and once you've got one of a set punched out, use the punched one as a die to help push out the others. 4. Get some 200-400 grit sandpaper. If parts don't go together without a lot of effort, consider sanding them lightly to remove burrs and make the parts fit a slight bit better. 5. Don't panic. Almost any of the small, fragile parts that you have a high likelihood of breaking as you assemble it? They've given you quite a few spares. For the other parts, you can likely glue anything that breaks. Have fun, and enjoy.

### ⭐⭐⭐⭐ Beautiful and mostly functional, though maybe I got a miscut unit
*by R***R on December 31, 2020*

I got one of these for myself since I like trick boxes, assembling things such as puzzles or models, and the "steampunk" look. Took me maybe 4-5 total hours to assemble, and I had to rebuild some assemblies more than once because I wasn't paying attention to directional arrows. The wood is fairly strong, not super soft like balsa, and very nicely laser cut. I work for a manufacturing company that uses industrial laser cutters so I appreciated how precisely and densely the pieces were put together on the wood sheets to avoid waste (a process called "nesting" in case anyone who might be reading this cares). Most pieces came out cleanly and I didn't need to do much sanding, but I did have to use a utility knife quite a bit to help break the supports. I did break one piece very early in the assembly, but that happened when I was trying to remove a wooden pin. Thankfully the piece wasn't a gear or any other part used in a mechanism, otherwise I wouldn't have been able to continue. They include some spare pieces, which I ended up needing so that's a plus. For the most part I am happy with my product. I wish they had included wax or some other lubricant (like graphite) but I had to improvise and used lip balm... We'll see if that actually holds up at all. That being said, I think I the cutting alignment might have been off for my unit, because the lid mechanism doesn't line up flush with the rest of the box and I couldn't make it happen no matter how hard I tried. This also means the key doesn't rest in the lid mechanism like it's supposed to, so the trick is more or less given away if you look carefully. Also, I'm not sure if this was by design or not, but the gears that are part of the lid lift assembly don't meet up on all sides, which makes the gear train a bit unsteady. I've included a few photos to show you what I mean. All in all, I actually had a lot of fun building this despite the frustration of parts not lining up the way they were supposed to. I am going to purchase a few more kits from this company and see if my luck is any better.
