Very Exciting!

I purchased this for my grandson who just turned 7. There are lots of small parts in the kits, but he can manage that just fine. The goal was that he completed the kits with his dad, and not independently. If the goal is for the child to work on the projects independently, then I this kit is more suitable for an older child.
