Review on 🧩 Discover the Fascination of Ugears Mechanical Wooden Puzzle Friendly by Ryan Olsen

I had fun building it and it looks great on the shelf, but I couldn't get it to work with the "Roller Pendulum" installed. Without a role, it ticks normally, but very quickly. Regardless of increasing the tension of the rubber band, adding extra lubrication, straightening out the mechanism, and fine-tuning, he was able to make it work like a 20-minute timer with a reel. put it in the instructions. "Will you hear a nice sound"?! Haha, was that supposed to be a joke in the product description? As others have pointed out, using a regular rubber band under tension will cause it to break down within a few weeks and require frequent replacement. So this timer is just for show at best and should never work.
