We offered this train for 3 years of our boy. It's a bit difficult for him to assemble the rails but there should happen soon. When he turned on the train, he was surprised, he was jumping around with eyes wide open. The sound effects are excellent, he breaks out put gas. He tries to cars, I think we're going to complete his collection. We are happy with our purchase and can recommend their eyes closed. We bought additional rails as we had read that the circuit is small, but for a little after 3 years is enough. Growing up, add rails, bridges, it will be more fun.
