My daughter loves her hoverboard! She received this hoverboard for Christmas 2019. Within a couple of months, one side stopped working properly - when she stepped on it, it tilts just to that side. We sent an email to the company we purchased it through Amazon (Veveline), and they got back to us right away to help us troubleshoot the problem. We simply had to reset the system and it works beautifully again. Thank you!
