hey all, my name is steve been vaping a little over a year now started out my newbie journey with an innokin itaste which really didnt last long then an istick 20w with nautilus mini good combo for work but the firing button gave out. So i moved up to a 50w istick with a subtank mini which I still have and use often. I really like the subtank mini tank so I got the new black sub box kit about four months ago more for the look of it, but sadly the firing button gave out and its past warranty time anyway im thinking about getting an ipv d2 to mate to all these subtank minis I have laying around or should I get a different mod?
