I use the Kanger Evod tank-style e-cigarette and I mostly love it. Except it inevitably starts getting too much smoke juice in the atomizer, causing gurgling, poor vapor production and smoke juice leaking from the mouthpiece. Yuck and bummer.
After tinkering around and trying various things, more or less to no avail, I finally did a search, all but certain that others in the vape community had encountered this problem. Sure enough, I did find several threads on e-cig forums, but no one seemed to have devised a solid fix. Except, that is, Deus Ex Vaporis, a/k/a the God of Steam. Check out his super easy fix. It worked for me. Hurrah!
