Instructions were easy to set up & charge car, remote and finger/sensor prior to Christmas morning. Purchased for autistic 7 year old as a sensory toy, and 3 year old siblings. The kids played with car all day, refusing to open other Christmas gifts. Long-life rechargeable battery, and second rechargeable battery included for when hours of playtime is not enough on the first battery charge (we did not require the second charged battery Christmas Day). Music & lights accompany the car that entertains moving in 360* directions. I will buy a second car for my another kid....
