I've had mine for a few days, and could not be happier with it. If you didn't know what it cost, you'd swear it was a high-end, hand machined mod. It's solid, great weight, and with a perfect fit and finish. I've bought classy lighters (remember those?) that were comparable to the quality of this mod - but spent hundreds of dollars for them.
I bought (and use) the Zmax that came out before this model (stainless steel), and couldn't imagine that Sigelei would improve the quality over that one - but they clearly did. I loved the stainless steel on my other Zmax (didn't care for the shiny chrome model) - but the finish on this telescopic is even better.
If vaping were mainstream, and big money players were in the game, you'd be paying a heck of a lot more than the $60 (on average) that we're paying for it.
I can't imagine why on earth anyone would still want to buy, or justify the cost of a Provari.
