I've purchased a lot of STEM kits for my kids, and this one is among the best. It's engaging, educational, and really demonstrates how alternative energy works in a simple but effective way. Highly recommend!
Easy to put together but it is more of a kids toy. It was interesting and will get me to a more extensive project.
My grandson took his time with every step in the process. It kept him off video games for hours. If your looking for Eye hand coordination this is a great choice.
Used it for an experiment on Earth Day at an Elementary School to show how BMPs work. Was perfect. Way better than what I was going to do which was to make my own.
Bought for my child's second grade class. They love to use this and learn new things together.
