I've been using the Smoketek 3.5ml tank and 1.7 ohm cartos as well as the 510 liquinator tank (3ml) and 3 ohm cartos. At first they worked great on my silver bullet at 3.7V, or my EGo-T battery. Then they started drying up on me even a brand new one wouldn't wick. I got a var volt lavatube and all was well for one or two tanks at 4.6V. Now I can't get brand new ones to work. Surely thay aren't all bad! What am I doing wrong? I fill the cartos and they dry up, won't wick, flood, or just plain old won't snap crackle and pop for me. Can someone please detail how to use these for me? I've tried every voltage, and several different ohms cartos. Now I am confused, frustrated, and just plain dumb and disappointed. So far my best experience is with the EGo-T tanks at 1.1ml, but they don't hold enough juice to last me a while. (I'm a juice hog.)
