I'm near the end of the tank (1 ml mark) and no gurgling whatsoever, just a smooth as ever vape. I just remembered badkolo had recommended I re-sit the head just in case it was not seated properly, and I cleaned the tank and re-seated the head, and badkolo is never wrong
, so maybe that was it? Oh Lord, a third variable, now I will have to start from the beginning all over again... jk hehe. But I saved that third wick and I can put it back, so maybe I'm not kidding after all.
