I completely second this.
Hell I don't even have a V2.5 hell not even a V2 provari. I have the V1 that I got used this past Tuesday, and I love this thing. I still love my mech's and Sub Ohming but I think it will be really hard to beat a Provari. I really wanted a ZNA but I can't justify the price now after owning this. Don't get me wrong I love the ZNA and I still want one. But I will buy another Provari first.
I saw something about a new v3 coming out and it got my hopes up, but I didn't actually get around to finding out the details.
