I need help with learning the difference's between Cool carts, Wow Carts, C2 Carts, Duel Carts, Clear Carts, etc, etc, for the KR808. Also why is a cart only good for 4-5 refills. It is because of the batting or the heating element (forgot the correct name). Who sells the best blanks? I like the Elite blanks, but if I don't keep the ecig upright, the juice will flow to the mouth end. I perfer the auto battery and use my passthru when on the computer.
