Review on 🧩 Discover the Fascination of Ugears Mechanical Wooden Puzzle Friendly by Veeravelu Tang

The design is a bit complicated, but not too complicated if you take your time. Parts can be difficult to separate and reassemble with the toothpicks provided. This prompted me to break the piece and order a replacement for the cost of shipping. Using a fishing line for a rolling pendulum is finicky at best. The biggest problem is the trigger mechanism. Waxed gears press on 2 waxed toothpicks as these are unlikely to reliably prevent the gears from binding or skipping. The "alarm" mechanism was a mystery to me until I watched a video and discovered that the activated lever makes a clicking sound when the device reaches zero. Ignoring the performance, it's solid. I like the idea of To use wax and cut toothpicks to use as nails.
