I've been vaping my aspire Atlantis tank 1 for around a year now and I've run into some dud coils before both Aspire and amigo. I switched to only amigo coils for a few months now. For some reason for the past 2 coils I screw them into the top, fill and when they start to get tight it pops and is only screwed into the bottom. (air intake) So I try to get it close to being tight and turn it right side up and it twists freely but doesn't seem to leak. Please help I have a feeling I'll grab for it one day and it'll just come apart and ruin my mod!!!
