I got them from a store called the E. Cig store, they sell the coils in individual little tabs, the first one I got which they put in the e cig for me worked fine, but the ones I bought and tried replacing myself didn't work at all like the first one did. I tried letting it soak, I tried putting liquid directly in the coil cotton, letting it sit for 15 mins, I just can't figure out what I'm doing wrong and I've spent a lot of money, the coils weren't cheap and I bought 5 of them to last me awhile and now wasted them, that's why I'm flustrated.
