I bought this car for the birthday of my little boy. He had a christmas carrera go circuit and he loves cars. The circuit is great, much like the small as great but what about that car. A lap of one and the engine idles. It is unusable in the state and my little boy was heartbroken. Therefore I asked for a replacement. Amazon was quick and no problem. But the car n has not even had time to do a lap that the wheel guide before been broken. So I asked for a refund. Good advice, buy a car carrera single (very strong) and avoid the cars bearing the image of cars or mario kart.
