Ok, on and off e-cig user...had the 810 style, would pretty much melt the caps off a 510 cart. Got a Spinner and some Kanger T3 Clearomizers, flood city..ok if I lightly drag on them I am ok as long as I do not do it too many times in a row. It is not the juice, etc..I just draw on it hard like you can with a 810 or a cigarette and several times in a row. Is there another cartridge out there that can take my smoking style? I am wasting juice like crazy not to mention I do not want to drink it.
