I have an Aspire Natilus tank on a ProVari with the beauty ring. I know nothing about how to work it other then pushing the button and vaping. Oh and how to change the PU... Whatever that stands for. My question is, for over a year now I have been vaping and mine always tastes burnt, it's starting to piss me off and I don't know what to do, is it me? Is my tank broken? My friends said my coils are 1.8 (again... Wth does that even mean) but she said they are running at 2.2.... Can someone please help me. I am so confused!
