I got this for my grandson who will soon be 6. Prior to him getting it I charged the battery pack for the suggested 8 hours, and it ran great. But when he got it approximately 3 weeks later it ran for only a moment, even though it had been turned off all that time. When I tried to take out the battery pack to recharge it I found that it is ridiculously impossible to get the darn thing out! I squeezed the 2 little clamps and tried to disconnect the battery pack from the vehicle wire every which way with no luck! My grandson has now come and gone and never got to play with the vehicle. I will have to bring it into a hobby store or ? and see if I can find someone to get the battery pack out. I would not recommend this item. With all the RC toys I have bought through the years, never have I ever incurred such a stupid problem with one. I threw away the box and am not sure if I can return the item, but I'm going to try. What good is it if you can't disconnect the battery and charge it???!!!
