Our hoverboard stopped working after less than a month of useage. It had 8 inch wheels. The hoverboard Glidecraft sent as a replacement (because the original couldn't be fixed) has 6.5 inch wheels and was obviously well used based on the scratches and dents it has. Sent them an email to figure out why we were sent a replacement hoverboard with 6.5 inch wheels and not 8. No reply ---and that email was on an email thread that they had been replying to for 4 weeks. Yes--it took over 4 weeks to get the inferior replacement hoverboard. I will never do business with this company or recommend them to any one.
