heya peeps, ok i have a Mini Davide glassomizer which i use with my eGO battery. I received the glassomizer last week, it came with three replacement heads and i'm already on the third head. i read that they're supposed to last about a couple of weeks each but after one day the flavor of my ejuice goes flat, and inhaling takes a bit more suction. my main eliquid is Blueberry Kona Coffee from Apollo, my other favorite is regular Coffee also by Apollo. both these eliquids are rather dark, and i've heard that clearomizers and glassomizers have a bit more trouble with darker eliquids. ok but i shouldn't be going through replacement heads every friggin' day. what the heck am i doing wrong?
