I just bought my first vape because I really want to quit ciggs! I've done a lot of research before purchasing I finally decided on the istick 20w I then bought a tank I saw online on sale thought I would give it a try with it it is the aspire mini Vivi nova bdc once it came in the mail I put it on my istick put the ejuice in and vaped it, it was giving off this burnt taste as well as a burnt smell I for sure thought I filled it up enough I don't know if it's the wattage or voltage it still is a little confusing I'm not sure if I should be setting it to some specific Vw or if it's just the tank it's reading 1.9 ohm on the istick so I'm not sure if I should be putting it at a certain vw for that reading and that kind of tank!! Help lol I really wanna quit ciggs and figure all this out * I also went ahead and ordered the eleaf gs air tank after reading around that was a good tank for the 20w but it's not here yet! Thanks I'm advance
