This STEM kit is a great project for kids who like building and robotics. The pieces fit together well, and the instructions are easy to follow. The finished excavator moves smoothly with the remote, which makes it even more fun to play with after building. It keeps kids busy and teaches them a bit about mechanics at the same time. Nice quality overall and a good gift for creative kids.
