i have been vaping a bottle of juice through a smoketech, dual coil tank with the chrome ends for a month now and really enjoying it. it came with a triple punched carto. (which is a beautiful thing), and i ordered a five pack of triple punched replacements. anyway, i wanted to load up a new one today for a different flavor, even though there was nothing wrong with the one that was in it. the first one out of the replacements was a dud, and the second would not quit flooding to the point that a normal draw would get juice in my mouth. the third one worked like a charm, so my question is...did i just get a bad batch? or, is this pretty typical in cartos? i have been vaping for 6 months now, started with a twist and a clearo, then to a vv box with a 306 atomizer and drip tip and then a lavatube using a combination of these setups, but somehow skipped the cartomizer thing until now. just looking for some other peoples experiences, cause i'm starting to wonder if i want to keep messing with it after leaving this initial "bad taste" in my mouth!
