Yeah, I've got a couple of IKV 2.0 ohm attys that weren't quite giving me the throat hit I like at 3.7V. So when I finish this tank of juice I'm gonna pop them in and see if I can crank it up a bit. Hope you get your adapter today. I don't think you'll be disappointed.
downside to the Provari is it does not like 1.5ohm attys so you will get that error. Well you have a VV so get a SR atty or a 1.8-2.0ohm and crank it up =)
