Review: Super cool! - 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!
Review: Great customer service! Great product! - 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.

### ⭐⭐⭐⭐⭐ Great customer service! Great product!
*by N***I on November 10, 2019*

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).

### ⭐⭐⭐⭐ Beware B11! Otherwise fantastic.
*by B***8 on January 19, 2026*

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!
