I am a newbe and must admit that you all have confused the buggers out of me.... I purchased a starter kit from a local shop that is made by Premium. It comes with 2 auto batteries, charger, and 6 pre filled cartridges. After reading most of this thread I'm glad I went with prefilled carts. I'm no scientist and frankly you all make it sound like you need a degree to know how to mix, fill, drag, manual vs automatic, this vs that..... holy cow!!! All I wanted was to get off analog (I think that's what you call reg cigs) but still be able to keep my nicotine cravings under control. So, the bottom line is.... for a newbe the auto - prefilled kits are not a bad way to go. You simply buy it, charge it up, and puff. After a couple of days you get the hang of using it and you are on your way to being analog free. I simply wanted to put in a good word for this way of starting. As a 35+year smoker I'm very proud that for 3 days I have not smoked a cigarette. That in itself is a miracle for me. JMHO
