Ok. After everything I've said, I'm thinking about ordering a few more packs of these things. Maybe the one I used today was just a dud. Maybe? When the others were performing, they were performing well. Right up to the point where I got that charred taste, which took about a full day vaping five, six, or seven times a day about the amount of puffs as one cigarette each time. How frequently can you vape using these cartos? I didn't feel like I was over-using them. How long should one complete fill up last in theory? I know all the juices are different, but I mean just generally for most of you how long does a completely full carto last and how often do you vape?
