I haven't used a tank exclusively, since I usually vape from two flavors during the day, but it still takes me about 4 hours or so to go through one tank on liquid and have gone through about 8 tanks of liquid since I got mine thursday around 3pm. I think the time is about comparable to a carto, but at least you can fill these up again, with a full 20 or so drops, as compared to maybe 10-12 drops on a carto after the initial filling of them.
Haven't had a problem with the paint peeling at the top of the atty yet and haven't had that problem on any other attys, not even ones I have used a cinnamon liquid in, but I have only been vaping a cinnamon liquid about a week now.
