Just like topic says, feel like my vapor is horrible for double coils @ .58 28G. Please watch video, all comments & suggestions welcome. I know my coils aren't perfect but, definitely had worst when I 1st started to build lol. I swear my single coils give more vapor. It's fresh VTC5 battery, dunno if I'm going crazy, not use to my Reo, something is wrong I dunno. just not getting efficient amount.. Ty Reonauts
