I have been an avid dripper for over 3 years. I had been looking at different tanks and wondered how well they work as to air-flow? I'm not wanting the type that you have to work on with wires and wicks....not that mechanical and don't want the hassle. May not want one at all as to the air-flow question. Don't want to cut down on the hit of the e-juice. If the convenience is there without the air-flow issues, it sounds desirable. Please let me know your experience with them?
