Make sure your little one is supervised if they are under 3. The cars are a lot of fun, but not made for little guys. My grandson loved them and they kept him busy for a long time. We lined them up and raced them to see which one was the fastest and he thought that was great. He loved the fact that they were construction vehicles because he loves that type of trucks. They are well made, but light weight so the parts may get broken if now handled with care. We like them alot!
