Just ordered 10 kangertech coils seeing as the one that came with my portank 3 mini is seeing a huge performance drop after 4 days,which I'm hoping was just a did or aomething.. I got the .8 ohm coils , and I use 50/50 mix of mtn dew flavored and sour patch flavored both are clear juices.what should I expect to see ? What are your guy's results?
