I quit the analogy the same day I started vaping....2/18/12. Since then I've converted 2, and am working on 2 more. The first 2 no longer smoke analogs.....the last 2 still smoke a few a day, but nowhere near what they were smoking! I consider that partial success.
. And have to agree with some of the others....pple say it costs too much to set up......that's bs! Only costs about the same as a carton of analogs to get a decent kit and get started!
