That's funny. The only ones I've tried are the CE5 and the iclear 16. Love the iclear16 it's putting the vapor out and has good flavor. Cartomizer tanks still are my favorite. Hotter vapor and way more of it. Plus the lack of hassle with keeping the coils wet. Clearos are easier when you're first starting out. The CE5 got my aunt off the smokesI'm pretty sure there isn't a clearo I havent tried. Care to make any suggestions?
