I'm what, 7 weeks into this adventure? I am enjoying my 78mm Volt autos right now (I have 3 batteries - some days I get through the day on 2, some days 3, and some days 4. When one dies, I put it on the USB charger & grab one of the other 2 that are already charged...rinse...repeat.) I gave up on prefilled cartos very quickly (w/in a couple weeks) once I discovered all the great juice flavors available. I have exactly one clearomizer so far. I toy w/the idea of an X2 battery and probably will get one @ some point, but for now I'm happily vaping away w/my current setup. Based on the experiences of many around here, I won't say that I'll never "step up", maybe to a Twist or something, but I really can't see myself w/a tank, mod, etc. I don't think it's necessarily so much that I want it to look like a cigarette (I kind of hold it like a pipe rather than a cig), but that I like it to look somewhat low-key, compact, & discreet. That being said, I don't leave the house very often (work from home & homeschool my kids). For those that actually get out once in a while

I can see where battery life, etc. would definitely be more of an issue than it is for me.
I say whatever works for you - if that's a Provari, go for it! If that's a 65mm Volt or a Blu from Walgreen's, go for it! Anything to get away from smoking!
