When I saw the cars for this game I got exited and bought all of them. To my disappointment, two out of the five I bought worked. One of them had no charging port and another two refused to charge and/or didn’t have a working charging light. I was really disappointed not only because the cars didn’t work, but the app was not the best and there was some poor translation from Chinese to English. The physical cars that you buy are 12 bucks apiece and might work if you are lucky. My advise is, save your money.
