Yeah what they said, the burnt taste it is very noticeable, tastes pretty awful suddenly imo.
Really though, in my experience the battery will die before the cart goes dry. I've had a Blu dispo, an Infinati or something like that, and one other can't recall the name. They all lasted me 1.5 to 2 days and then the battery died. But then I'd estimate that I got about one to one and a half full packs of analogs worth (maybe a little less) out of it (they advertise as about two packs, but we all know that is B.S.), and if you figure 15 puffs per cigarette, 15 X 30 is about 450 puffs, AT MOST, so yours will probably be dying very soon. Unless as someone asked above, you are talking about a dispo carto and not a dispo e-cig.
