On ce2 i was not able to use anything thicker than 80pg/20vg or it would wick no flavor . That and the other 10 problems i had with them . The SS eliminated one of those problems (plastic taste) but not the rest . Iv never even got a close to accurate ohm reading off any of them either . Some people do love them ce2's though although they did win the worst ecig product award along with egot tanks .
