Review on 🧩 ROKR Puzzle: Perfect Mechanical Construction for Adults! by Daniel Drury

I got it as a gift. The fit and details are amazing! It requires considerable finger strength to hold the pieces together. Even when assembling very small parts, a great deal of manual skill is required. Sandpaper is included in the kit to bring parts that are too tight together. I only sanded one part, otherwise there would be problems with the assembly. There were very few errors in the instructions and they were all minor and easy to correct. The instructions were IKEA 3D drawings, only on steroids! I finished the build in about 12 hours and it worked! It was a bit embarrassing that there were about 10 left. I looked at the instructions and came to the conclusion that these are replacement parts. It would be fun to display this in my office. Unfortunately I am 66 years old and retired. Still a 14 year old at heart!
