I have been vaping for about a month ... cig free for a short time so far. But ya'll have freaked me out a bit concerning atty failure, so I stockpiled. I've been hitting the PV HARD and constant like it is the "straw of life" to get rid of the cigs. I've been using the same two attys on a 510 and the eGo doing nothing more than blowing them out each evening. What am I looking for when my atty goes? Do they simply stop getting as hot? Will they give off a burnt taste? When do I change them out? I think I'm doing ok for now, I just want to know what to be looking out for. For me it would be easier if they would die in a fanfare of sparks and popping noises so I know for sure!!!
