So I started vaping about 2 months ago using the standard non-rebuildable vision clearos (with the long wick) and I enjoyed them for the first 2-3 days but after that the taste started going south and I got a lot less vapor from them. After a good cleaning in vodka they would usually pep right back up but this time only for a day or 2 max....I'd clean it again and get another day or so out of it before I had to switch to a new one. (BTW I'm using an eGo 650 and an eGo 900 battery right now....) My main question is, WHY? I was told these tanks ought to last for 2 weeks to a month and even longer in some cases depending on how heavily I vaped. Do I actually vape enough to more or less "use up" a brand new clearomizer in less than 2 weeks? I can tell you that I vape a little less than a 30ml bottle of fairly thin, lightly colored tobacco flavored juice every week and a half or so although I have gone through a 30ml in a week before once or twice. I don't know if it matters but when I vape I draw into my mouth and inhale from there.....I know a couple of fellow vapers I work with that inhale directly from the e-cig which IMO seems weird if you're vaping a flavored liquid because when I've tried that I get very little flavor which is one of the reasons I vape. These days, I've tried a DCT tank which I honestly wasn't too impressed with since it didn't last any longer than the old tank and I had zero luck trying to clean a dct carto. Right now I'm using a Kanger MT3 and I still go through a coil/wick per week but at least with that I get a better flavor for a longer period of time.
