It's difficult to imagine how an e-cigarette can cost twice as much as others in it's so-called class and be so popular. You read the comments of Provari owners who paid their hard-earned money to own one, nary a disappointed owner can be found. There are literally scores of Provari threads on ECF, most of them beginning by asking something along the line of, "Is the Provari worth the money." And every thread gets the same responses from owners. It isn't the universally accepted standard for quality and consistancy for nothing. It truly is in a class of it's own.
As many owners admit, they had spent hundreds of dollars on mid-level Provari knockoff before finally buy the Provari, regretting not buying one to begin with. As the great PBusardo is quoted, " I have seen one, I have held one. I have vaped one, and I have owned one. And now, I GET IT."
