If the guy had said it was a knock off, and that it was still I good vape, I'd be fine with that. Knock offs are cheaper. It's that I'm not told, and I can't get it to charge without the battery dance that is making me angry. Once charged, it works great! It just is a horrible pain to get charged. It should be just plug it in till the light goes green, but it never works out that way. I e-mailed the guy I bought it from, waiting on a reply. I was nice about it, he may not know.
