Jetson Spin All Terrain Hoverboard LED

I bought this item for my son and after 1 week of use, it kept shutting off fully charged then stopped working all together. I reached out to the manufacturer without a reply. So, I requested a replacement from Amazon instead. The replacement came, plugged it in to charger for the first time and it NEVER turned on! I called Amazon last week and they told me they would send me another replacement arriving June 3rd and to discard the one I had. Well, it is now June 10th and I haven't received a 2nd replacement so I called Amazon again. The didn't know what I was talking about and refused to replace the broken one and to send the old one back AGAIN! Thank god I didn't throw it away as advised from the other Amazon representative. They said there were no replacements available when I complained and told me to use the refund to buy another one. I asked, "if I use the refund to buy another one, since u stated to me there weren't any, why cant you replace it and keep my money?. They didn't have a reply that even made sense. I am EXTREMELY dissatisfied with Amazon, Jetson and their crappy product. I will NOT be buying this for the 3rd time and advise to stay away from any Jetson products.
