Review on Amutoy Assorted Colorful Clockwork Classroom: Engaging Educational Toy for Kids by Sean Fabacher

Unlike most plastic wind-up toys, these toys are screwed together and can be taken apart. I'm using them as part of a mechanical movement tutorial, so that's an unexpected plus. There is a lot of variety in this set and I predict it will be a fun way to start a lesson. I can't say anything about the durability of the parts - only one of 24 parts didn't start properly and didn't trigger properly.
