Haven't used my Billow in a long while, but I think that was the one you could flip the AFC ring over and it was a lot tighter... might give that a try.So I noticed my Billow v2 AFC ring is really loose, and I don't think it was this loose when I first got it? Looks like the tiny bit of juice that has gotten into it has made it loose. Anyone else have this issue? Almost every time I go to hit my mod, I have accidently bumbed the AFC ring and turned it to closed. Kind of annoying but its still such a great tank its not that bad, but just curious if anyone else noticed this or has a fix! Thanks!
