I have been an avid Marlboro smoker for the last 15 Years, and in the last year I made the decision to do something different and have tried many different vapor e-cigs to satisfy my needs. The Lava Tube is the first e-cig that I have not reverted to the occasional cigarette to get the feeling I needed. With the ability to adjust the vapor and get more when it is needed, I don't feel like I am left wanting a cigarette at all. Absolutely is the Best on the market and worth its weight in gold. You wont be sorry with this one.
