I filled my pre-filled empty cartridge (Mistic) with my VG 12 juice and let it sit for 12 hours....I have maybe vaped ...I did not exactly count but the vape seems to have diminished already...maybe less than 20 vapes....is that normal....Highbrow juice....my battery is charged (tested it on another cartridge)....any helpful hints or is this just the way it is....I may have not filled the cartridge enough (saturated it) I was scared of it overflowing into hole as the tutorial videos seem to stress....thanks again...I am new at this remember and just need some feedback....
