Well yeah. The clearos come to find out or maybe it's wrong are using Attomizers with wicking. Thanks use the cartos with fill? And the airflow controller has been said to make the carto get too hot too fast. Better to live with the original design of the carto for best results. I used tanks and cartos with one hole punch as my second device. If it gets too dry I prime it. Love that prime. Gives a new stronger tasting hit for fun. Sometimes I punch a second hole. Hate if they flood. The reason I changed from just cartomizer was that dry thing. You can prime it by sucking without pushing the button a couple times but with the vertical coil it needs som up top too for a great ful tasting hit or more. Finally I like Pyrex. None of the "tank" and atty clearos have that unless you get in to rebuildables. It's nice to have a variety
