I've bought three batteries, six tanks, several starter kits, endless types of coils.....I always have to come back to my original Endura T 22, because nothing else works. For example, my most recent purchase was the Kanger Protank 3. No matter what juice, coils,or batteries, it does nothing but produce a burning taste or a faint wisp of vapor. Same with Wismec, Smoktech, Innokin, Joyetech. I know about priming, I know about ohms, etc. Doesn't matter. Nothing works.
