I bought this for my 6 year old grandson and he loves it; however, being 6 wanted it to work right out of box. It has to be charged and the more he fiddled with longer charge was taking. Finally, we put it up high enough charging that finally charged the 20 min recommendation time. Battery life is short and instructions are correct best play space is floor or very flat surface. No carpets, outside, grass, gravel will stop car dead in its track. So the kitchen and hallway are now racetrack central. It's cool using it with iPhone and iPad. It not necessary for full play advantage
