Hello, unfortunately I can't help you there. Our cars are still ok. Unfortunately, one of the hand controllers has broken down. I reported the damage to Galaxus as a warranty claim on their website, but I didn't even get a response from this super company. My experience so far with Galaxus has always been top notch. I won't be buying anything from them again for the time being, because they leave you out in the cold. Be careful when buying from Galaxus!!!!!
