Hello all, thought I would post this for others that may run into this issue. I just purchased and received my LT 2.0 today. I had problems with it almost immediately after receiving it. I used it for a bit then it just shut off randomly. I replaced the battery because I knew the one I put in was almost dead. A little while later it did it again with the new battery, then again twice more. All of this happened within 8 hours of getting it. I called Volcanoecigs.com and asked them about it. He informed me this has come up a few times and gladly sent out a replacement with no problems. So thought I'd let everyone know in case it comes up for anyone else.
