i should be recieving a package of 510 cartomizers today. this will be my first time using cartos so i read a lot about them but im still not sure how i should fill/refill mine. i'd like to use the condom method but i'm not sure on a few details. like should i put the mouthpiece or the threaded end in the juice? i just bought an auto battery as well so i'm afraid i'll ruin it if i do this wrong. if anyone couls break down the procedure for me i'd greatly appreciate it. also should i do anything different the first time i'm filling an empty carto?
