I have recently purchased my very own Lavatube! It is awesome. I love everything about it! The drip tip is easy to use and sleek. As much as i do like the drip tip, I wanted to not have to drip every 10 puffs or so. So I invested in a Dual Coil Tankomizer. I was impressed with the cool design, but was baffled as to how to use it. Youtube i ventured off to and found out how to fill it, and that it needs priming just as if you were going to drip into a new cartomizer. It worked for a bit no problem but once it used up the liquid i used to prime it, it seems that it isn't absorbing any liquid at all. No "auto-refilling" like it's supposed to do. That burning flavor of an empty cart is all i'm tasting. I know i didn't flood the carto, and there isn't any sealing problem. Can someone explain why my tank isn't working right?
