ROKR 3D Wooden Puzzle Mechanical Treasure Box Model DIY Brain Teaser Projects for Adult Age 14+ Birthday Gift Educational Toys Wooden Puzzles for Adults

Very cool build! Complex and satisfying. Beautiful and functional. Love that you can build and set your own lock. I’ve tried a few different 3-D puzzle companies and ROKR is the best. Great customer service!

The treasure box is very interesting, and works great! The instructions are clear, and well written, I had very little problems with assembly. I will note that you will need some type of heat source for the construction, because several times during building I was required to calibrate some parts with wax (which is provided in the kit). The only complaint I have about the product is that, like some others have said in their reviews, SOME OF THE WOODEN PARTS ARE VERY DELICATE, AND SHOULD BE HANDLED WITH CARE. While building the treasure box, an important piece of the lock broke, and I couldn't fix it. So I contacted the company, and they were very kind. I told them about the broken pieces, and they nicely shipped me a completely new kit to replace the last one. It arrived within a week, and was in perfectly good condition. I finished construction without any major issues, and now it is sitting in my room, storing some of my things.

Be careful with the gears marked B11! I had no difficulty with breakages throughout any of the rest of the puzzle, but broke 4 of these things in a row and had to order replacements. Strongly recommend using another bigger piece like the extra numbered dial as a tool to push evenly on the B11s as you’re putting them on the poles. Replacement pieces came easily and were hassle free. Outside of the B11s, I really enjoyed this kit, being able to make my own combination lock, and the final product is a really nice piece with a lot of fun features. If I had to say one more thing, the back piece does not lay evenly in the circles cut out for the knobs because of the way it is cut to be able to curve. This is really a minor nitpick. Will be looking into more ROKR in the future!

I actually was eyeing the marble run first, but since I haven’t done any from this brand before, I figure I should start with something simpler. This is a very well thought out 3D puzzle, and the finished product looks exquisite. My problem is really with how hard it is to get some of the pieces in place. I mean I have very little grip strength, so the later steps where you have to wiggle and force a piece in place was very difficult. And the wooden pieces aren’t strong enough to withstand some hammering. Luckily, with the help of my 8 yr old toy hammer and my trusty tweezer, I manage to softly bang some of the edge in without damaging the wood too much. The instruction isn’t exactly crystal clear, took me a page or two in before realizing pieces with + sign next to them are extra pieces. And I was kind of hoping my lego/puzzle savvy 8 yr old could have enjoyed this project with me. Nope, he might be able to follow the instructions, but to build this thing, a child needs to be pretty advanced in manual dexterity. Anyway, it took me about 2-3 hours, mostly trying to figure out how to bang/wiggle things into place. There were a lot of doubts as to if the finished project would actually work or not. It did, and frustration aside, I am impressed with the design. Definitely worth it if you enjoy building this kind of puzzle. Now I am thinking about getting multiple others to build and gift, since you can hide trinket in there.

Cool engineering in the design. If you ever wanted to know how those dial combination locks we all had on our lockers work this will show you and you choose what combination you want as you build it.

This was a little more challenging than expected but I like that. Only one problem that had to do with setting up the combination. It turns out that the numbers at the start of the instruction manual are numbers NOT to use. The numbers at the end are what you need. I had a great time assembling this little gem. I appreciate the spare parts. I did break one of the rubber bands. I had to use a tiny bit of cyano glue on one of the connectors for the sides. A minor problem. To be expected because if the needed thinness of the sides. I like the cutting measurement tool. It made cutting the dowels much easier. I gave the box to my wife who is thrilled with it.

I got the treasure box and this was my first purchase for a Roku puzzle. I was excited to receive it as it was meant for a 11 year old science-oriented girl. The instructions were also not very clear and took a lot of time to decipher. The pieces are really small and the construction was sometimes very challenging because of that. I would suggest using tweezers for some of the construction, especially the ones where small rods have to be cut. It might have been helpful to explain that you can slid the rod in AND THEN cut them, instead of cutting a 6mm rod then trying to push that through something tiny. It could be really frustrating to have to do that 4-5 times in a row. Even as an adult trying to complete this, it took hours and days to get over the frustration in order to complete it. I don't know how the other puzzles are but I would not suggest this as a first puzzle.

Instructions were clear, it requires patience as it has some small pieces to put together but its fairly easy to assemble. It works perfectly and its s very cool little puzzle safety.

The instructions are easy to follow, and it's relatively easy to build. There are extras of some of the more fragile pieces which is great, as I broke one of the small pins trying to assemble it. Don't skip on waxing the parts where it says to, otherwise the gears may not turn nicely. It took a few hours to build, and would be a great way to spend a rainy or snowy afternoon indoors!

The quality and size of this was perfect. I thought however halfway through the project was over - as a key piece of the puzzle that is meant to bend broke (even though I was extremely careful with it). However to my surprise the company anticipated this and had spare parts - which worked out really well. The box functions as intended and looks extremely nice. Ordered another kit from the same company and looking forward to putting it together.

This was fun, and awesome in so many ways! My ONLY grief, and why it doesn't get 5 stars is because the actual volume of space inside the box and in the lid to hide trinkets is sooooo small. Would make a very unique engagement ring box but, otherwise, I can't see what you would put in either space. Bummer.

This was a gift for my 13 year old daughter. She LOVED it. There were a few parts that were tricky and she needed some help, but for the most part was able to do it herself. Very thankful that they gave some extra parts as a few parts can break when trying to assemble. This is a gift I know she will treasure and keep for a long time.

Great quality with no issues. Came as described.
