I haven't posted in this thread for a while, mainly because I have been so happy with my Provari. It suddenly occurred to me that perhaps I was being rude by not posting. The fact is, I've been using a Provari for about a year and a half now. My Provari has never failed me despite the fact that I sometimes tend to abuse it a little. I would like to thank ProVape for providing the community with such a wonderful product that is so easily obtainable.
