If you do not want to smoke, but are interested in vaping, just drop the 'ciggy style' mentality.
Buy yourself a good, mid-level, robust model. Yes, grab an eGo, one of the various new clearo/carto-tank models out there, and a charger, some juice, and adopt your new habit. It is not smoking. It is vaping.
Your 'ciggy style' is a small battery. It is not going to be there when you need it. Four or five years ago, I could understand wanting something more discreet. People are aware of these far more now, if they aren't, why hide it? Look around this forum, the internet, people are excited about these. Share, show off that freaking flashlight/lightsaber.
WE know we feel better. WE are seeing that zombie ... island of cigarette addiction fade into the distance. Why not share how we're getting the hell away from that awful place?
Yeah, sorry, do as you will, but I'm just venting a bit. You'll find you love vaping enough that you'll wish you had just gone straight for something durable, reliable, available, and versatile versus that cute little kit out of France that looks just like a Pall Mall.
