I guess what I need to know most about the tanks is, how long are they good for? Can you use them indefinitely, or do they somehow become dysfunctional with use/time?
Also: I'm at home all day, so I just keep refilling the same tank. I've been using this one all day, and I notice some moisture bubbles in the part of the tank where the e-juice is not, just inside the opening from which you draw vapor -- what is it, what causes it, does it matter, does it indicate I need to clean this tank, or toss it, or what?
Thx!!
