After starting with a couple Titan batteries with cartomizers I decided to buy a Dial-a-Volt and some 6ml Dual Coil Metal Tanks. That order is on it's way to me. My questions are: Will I have to mess with cleaning/replacing the cartos inside the tanks very much? If so, how often? What are my options as that goes? I am trying to make sure I have all that I need to keep on vaping with no interruption. Thanks all!
