I dont have a single bad thing to say about Provari because, like you said, I've never owned one. I find it hard to take someone serious that is willing to bash something that they have yet to try. Is it expensive? That's all relative to what someone wants to spend on vape gear. To me, it is. So if I was going all out, it wouldn't be on a Provari because I have different goals than others. Just my .02.
