I am thinking of buying Joyetech eVic Vapor Intelligent Cigarette VV/VW Upgradeable today. I've got about 15 different e-juice flavors to try out. I don't know which is the best way to do that. I know with tanks, one could clean after every use. When I first decided to vape, I never thought there would be overwhelming information. I thought I could buy a simple set and then happily be on my way to analog freedom. Well, anyway, I've narrowed it down to eVic and ejuice. Now I get to overstuff my brain for tank or whatever and tip.
