The title pretty well summarizes my questions. Curious to know what your fav sub ohm tank is and more importantly coil life. I gave up on factory coils little over a year ago when Kanger had a season of complete failures. I've been happily rebuilding sense then, mostly dripping with the occasional Kay fun build. Very knowledgable on ohms law and battery safety. Anyways I've been considering giving tanks another try for kicks and giggles. My vaping priorities in this quest are flavor and coil life.
