I'm new to
vaping also. I first went with a cigarette-sized pv and about a week later went and ordered an ego because the carts and
batteries weren't lasting nearly long enough. I had smoked for about 14 years and had fluctuated anywhere from three or four cigarettes a day all the way to a pack or more during that time. I noticed that I vape way more than I smoked and the regular sized unit just wasn't quite enough to satisfy me. My original was the Volcano Deluxe Kit and I turned around and ordered the Inferno with Mega Cartomizers just over a week later. It's nice having the smaller Volcano for taking out to vape without drawing attention but if I had to choose one, it would definitely be the Inferno. I've realized that if I had to do it over again, I would have got a 510 (probably the Magma but other brands would have worked too) instead of the Volcano because it would have been much more practical for my
vaping habit than the smaller Volcano. (The size difference between a pv and a cigarette is only really noticable for the first few days. After that, you won't even notice.) There's no doubt I would never get rid of my Inferno though. It hasn't taken long for me to bond with it and for it to secure a very special place in my heart.
Hope this helps you avoid the first purchase mistake I made. Since getting a pv, I haven't touched a regular cigarette. Hang in there, the research you're doing will definitely pay off when you do make your purchase.
