Review on 🔧 Unleash the Engineering Genius with UGEARS STEM Gearbox Model Kit by James Pfettscher

This STEM kit is really well made. The parts are easy to separate from the boards, strong and perfectly matched. I'm used to the "tune" fit of many of these wood sets, but it was a pleasure to build without the need for tuning. It's difficult, but the instructions are clear and easy to understand. I would have no hesitation in giving it to a younger person (8+) but I would say it could have been more fun with an adult. It is important not to rush (as they say, measure seven times, cut once). I haven't had a single breakdown, but I have a lot of experience with these kits. There are plenty of spare parts for all cases. Great job UGEARS!
