Hey guys, I figured this would be the best spot to ask my question. I use the Kanger Protank 2, and buy the atomizer heads in bulk so that I have enough heads to last me a while. I was talking to a fellow vaper at work the other day, and he mentioned that his atomizers last him a month or so before he has to clean them. When I put a new atomizer on my Protank, I get 2-3 days out of it before the juice gets really dark and I need to clean the atomizer. After this, I need to clean the atomizer at least once a day to prevent the juice from getting very dark, almost black. The atomizer itself only lasts about a week if I'm lucky, before it just stops performing to acceptable standards. I was wondering what I am doing wrong here. How can my friend's atomizers last him a month and mine last barely a week? Given, I do vape a lot, but I didn't think it could make this huge of a difference. Last weekend, my atomizer just stopped working in the middle of my work shift. Had plenty of juice, just wouldn't produce vapor. Tried different batteries, and still nothing. Went home and changed the atomizer and it worked fine again. I must be doing something wrong here. Can anybody help me out or give me some ideas on how I can make my atomizers last longer and save some money? Thank you!
