we bought this car for our 5 year old son. Big scare unpacking: After charging the battery and setting up, it does nothing happening, it was not working. and by looking carefully we realized that it was a contact that was not done with the battery. just to straighten the rod. and since nickel. it rolls quickly, both on concrete than on gravel. The battery is quickly charged and discharged reasonably. we had time to play well. remains to be seen if it will last over time. the look is nice. by against the remote is big for small hands. for now, satisfied.
