I kept an old atomizer that had a ruined wick, and I use it (sans spike and wick) in an extra eRoll I have for dripping sometimes in the evenings or especially to try new flavors. The vapor volume and flavor are heavenly! A couple good drops is all you can do at once but you get half a dozen monster hits from it. Easy to do a quick dry burn for cleanup and I use a new dry tank. You obviously have to keep the device pointed down to prevent messes. Just curious if anyone else has used their eRoll this way.
