Ive just created myself here on the forum, Im vaping my new MVP, with an I-30 clearo. Very exciting as I have smoked my last cigarette 48 hours ago. So I dont know if I over-filled or filled wrongly or tipped my unit to much with it full of liquid, but I got that gurgleing like it was flooded. So I unscrewed the tank from the mvp, and just put my lips around the base, (be careful not to put your lips on the little threads, unless you want them to go numb from the E-juice) and blow out through the tip as many times as you need and that seemed to clear it! Anyways whats the difference between a clearomizer, cartomizer, and atomizer?
