No matter what atty/carto/tank i buy they get a rank burnt taste!! So i got these cartos from provape with my provari and it did read 3 ohms so i cranked my voltage up to 5v and ewwwwwww all i can say.. cant go any higher then 4.5 or it just gets the worst taste... i bought a provari for 6v vaping and havnt been able to vape at 6v yet..
