I bought 2 I’d these. They’re 5 year old twins and they loved them as soon as they opened 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. Batteries in and off they went........straight to the kitchen! 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, Two boys were racing them. This was a good buy! Thanks.
