Same five e cig rigs, same tops, same bottoms, same vapers corner juice usa mix, same supplier for coils, I buy 50-60 at a time, and each pack of 5 is doing it. I called them to see if any one else had the issue, and they said no, but Im sure they dont want a mutiny on their hands..... I saw somewhere on line that "EVOD is making their coils more resistant" whatever the heck that could mean. I have the standard get up so Im guessing thats the single coil evod tank??? The suggestion of "going to an evod 2, protank 3 or an aerotank that all use the enclosed dual coils" Arent those coils like alot more expensive? It was all of a sudden that it happened, on all 5 rigs, at once. Maybe bad batch of juice? Im going to try to clean coils, I saved them to take them back as faulty.....is it better to warm wash and dry burn or throw it in vodka, then drink the left over vodka till I dont care any more? Instead of vodka, can I use 50% alcohol for cuts and scrapes? Thanks everybody for you input! I dont want to go back to cigs!!!! I will check the coil like sunshine suggested, but how do you know its shot? What does shot look like. gail
