I only get (if im lucky) about a hour out of a standard cartomizer before getting a burnt/dry taste because I chain vape too much. Might want to look into ce2s or tanks. This is just my opinion, theres tons of people who love cartos, they make them in XL sizes, low resistance, high voltage, dual coil, tripple coil and probally other models that I aint heard of. I just dont like the chance of burning polyfill so I stick with atomizers and ce2s wich don't have any filler.
