My grandson loves his. I bought it so he could have fun learning mechanical and building things. Using his hands and mind together to also build motor skills. He just loves disassembling into vehicles and reassembling into a robot. They remind me of transformers. He spends hours honing skills while playing and having fun doing it. It brought great joy to me seeing him enjoy his toy. I would encourage anyone who is interested in giving their children or grandchildren an educational toy that they will truly enjoy them buy this one. There are 3 to choose from so order early for Christmas it isn't far off.
