Pretty new to vaping and really like it. Have only used "minis". My wife just got a starter kit from V4L and the cartos don't seem to last very long at all. I'm really pleased with the fact that I haven't smoked in 3 weeks now and am looking at different kinds of APVs and am trying to decide what model would work for me. Maybe a Lavatube? ProVari? Are they reliable? How long do batteries last? What would a good "starter" model be? I like the idea of variable voltage and the variety of flavors of juices. This website is great and I very much appreciate the info available here!
