i've never had an issue with my protanks or evods - and most rba's taifun KFL etc are bottom coilers

Are we talking about leaking, or just condensation?

Unless you have done something silly, like shoved juice down the tube, or something heavy handed, like smashing the heads in cross threaded or damaged any of the seals it is impossible for a protank/davide to leak. Even if they don't work (ie, no connection or coil knackered), the protank/davide will not leak. If the post is seated correctly onto the head, they will not gurgle. I'll even go so far as to say, that if everything else is as it should be, they won't gurgle or leak, even if you forget to put slide the silica grommet over the post or use them without additional flavour wicks. But! and there is always a but! If your battery has not got enough guts to provide power to actually vapourise the juice your eager sucking is pulling onto the coil, then yes, a gurgle or three is to be expected.

I have had a few issues with iClear 30/30S`s gurgling and leaking so i don`t tend to bother with them so much now which is a shame as they give a good vape when they work properly. Keeping them below 2.5ml full seems to help, as does removing the top "flavour" wick in the 30S heads.

I have about 10 Aerotanks now and have had pretty much zero issues with them, even running them to almost empty, as long as you make sure the heads a screwed in properly they have been fine for me.
In fact the Aerotank has become my "go to" device now as I get virtually no bother with them and the heads are a doddle to rebuild.
