I bought a Spinner 2 on Ebay a week ago. I'm fairly certain it's authentic but I could be wrong. Anyway I had been using it most of the day just fine when suddenly it quit heating the coil. The button lights up as it should, and it powers on and off as it should but it won't heat the coil. And when I plug it into its charger the power button does not light up at all. I've already messaged the seller but they haven't responded yet. I've searched for Spinner 2 problems but never found anyone else to have this problem.
