I recently acquired two cerotank v2s with the recommendations of many ECF members and so far its just bad. I'm using the aspire 1.8 coils and I'd say I get good flavor from maybe 1 in 20 draws, the rest being so harsh you can't even enjoy it! This is with 60pg/40vg juice, I've tried 3 different coils and its the same in both tanks doesn't matter what voltage I'm at 4.2 or 5 volts or how long it sits for. What's going on here???
