I bought an 1100 mAh ego twist battery online, and I received it Nov. 4th. Today (Nov. 11), I went to class for a couple hours, and when I got back my battery wasn't firing. The button lights up, but it doesn't make that typical vaping sound and no vapor is produced. I read that the pin can get pushed down and it won't make contact, and that you just have to pry it up, but I can't seem to get it to come up at all. Is there anything I can do to fix it, or am I pretty much screwed?
