I went out and bought one, the first day went pretty good with them, but after that I transitioned back to smoking regular cigs. Maybe it was the type/flavor I bought, I don't know.
Here is a tip for you though...Do not--DO NOT, put them in your back pocket and drive home fromt he grocery store with it there. Apparently sometime during the trip, my wallet got into a fight with the e-cig and held down the button. By time I got home and pulled it out of my pocket, the thing was so hot you didn't want to touch it. Makes me wonder what would have happened if I lived a few more miles away?
