I've been vaping my Volt since Fri/Sat. I've recharged twice (both batts) and still have decent vapor and flavor coming out of my "trial" Cowboy cartos. What the heck? I was a pack a day smoker. Yes, I've seen a bit of diminishing on the vapor as this current night has gone on, but damn! Am I really going to get at least a day and a half out of a carto? To be fair, I rarely smoke during the day, but I never expected this when going to vaping. I didn't smoke all day but just hammered the analogs at night. Batteries (78mm) are lasting like champs and I'm not using anywhere near what I thought I would with the cartos or juice. I get that everything is a YMMV deal, but is anyone else plugging along and feeling like they are getting much more out of their cartos or refills than they expected? Maybe I should just buy some Cowboy juice and call it good.
