Im new to the E-cig thing myself. I bought my first one on March 8th and was smoke free until St Pattys when I was out drinking and my battery died. Thats bad news for someone who recently quit and ended in a pack of cigarettes and some Djarums but since then I got back on track and haven't had another relapse. Its good to see others as well have found an alternative that still gives the joy of "smoking" but without the hazards. To the point, I always have a tank in my atty. I bought multiple ones because I work 12 hour shifts and find it easier to have spare pre-filled tanks on hand rather than a bottle but as one comes out another takes its place. I also have another e-cig that I use drip tips and carts with when i want some higher voltage vaping but the tank system on the Ego is such a convienience when you are on the go.
