Hi there. I'e been vaping for 6 months. Started with 510 cartomizers, moved on to ego-c tank system and then settled with ce5 clearomizers. The clearomizers are the best tasting and they're not too bad to clean but i hate having to keep buying new heads. Can anyone recommend a similar thing that has screw terminals for making your own wick/coil? I don't mind it being a bit larger in diameter than my 650mah ego bat but most of what i've seen is huge.
