I have to put out Thanks to everyone out here for their vast knowledge in this complicated world of vaping. I bought a cheapo cigarette looking e cig a couple of years ago. It lasted about 4 hours before I was back to smoking analogs. Fast forward a few years and I see a few people with the provaris get much better vapor production than the cheapo provided me. Started research and brought me hear. I went big with the provari and started on Thursday night and haven't had an analog since. For me being a 1.5-2 pad Marlboro Red smoker for close to 20 years now, that is huge. Its not easy, but its working. Without the knowledge I picked up here, I would not have known where to begin. Thanks again to everyone and keep vaping!
