Be very careful buying from this company. I bought a C1 hoverboard from them in Feb 2021 and when it arrived it didn't work. The battery is completely dead and will not charge. When you plug it in the charger shows a green light as in it's finished charging but the battery never charges. It arrived dead and no amount of charging will do anything. I have sent emails and got no reply. Tried to call and the number is out of service. I think these people are trying to offload stock that has been sitting in storage so long the batteries have died, despite advertising the C1 as a new model for 2021. Fortunately I paid with PayPal and have started a claim against this company. I would strongly advise that you do not buy a hoverboard from these people. They are untrustworthy and there is nobody to complain to to sort out the problem. The warranty is worthless if you can't reach them. What i have is an expensive paper weight.
