They went straight to the kitchen, a few choice, words from dad and i took the boys and their new toys outside these. Cars ran on the grass, the sidewalk, the asphalt, the hardwood floors and the carpet. They were appropriate for both the boys ages and by the way after dinner, dad and the uncle were racing them. This was a good buy thanks. Our three and a half year old grandson also loves his remote controlled car. He immediately figured out the necessary techniques to operate this vehicle. We had also gotten a similar car for his five year old brother. We did get them with different frequencies, so they are happily racing each other. This was another gift giving win for the grandparents who have just been waiting to give them remote, controlled cars – s zuba – i purchased this for my granddaughter and she loves it. Unfortunately, for her, the adults at her birthday party loved it just as much and used it more than she was able to. I bought two eyed, these one blue and one red for the boys. I watch they’re five year old twins and they love them as soon as they open them. They work great and are a lot of fun to play with. They are easy enough for them to learn how to use the remote and have a great time playing with them. The only issue i found was the battery. I didn’t know it took a 9 volt which is not a standard battery.
