It's a problem on the forum, certain brands like Provari and Reo have strong FanBoy followings. If you give a negative review you get flamed.
You'll probably be happy with the Provari if you plan to use it in Plain Jane Vanilla Vaping.Understand that it won't work in Sub Ohm Vaping and has a 3.5Amp limitation. I believe that 70-90% of the vaping community vape in the Provari tolerances.
At this point in time there is no VV unit that can match Provari in terms of quality and ruggedness and Warranty. It is Pricey but you are getting an American Made and warrantied product.
One of the problems with most Chinese Manufacturerd VV Mods on the Market is that you have Hit and Miss Quality. One person buys one and it works great, another person buys one and it's defective from the Go. Also many don't hold up for the long term.
The Provari is not Hit and Miss only a very small percentage ever have a problem with the Provari.
Value is in the eye of the beholder. Saying something is not worth the money that's a judgement call.
Me I was willing to pay extra for the quality and don't regret it. But that was 2 1/2 years ago. Today I probably wouldn't buy one because my preferences have changed. I'm into bottom feeders and also in VV I've found the Itaste MPV to be a very good unit. Definitely not Provari quality but I can buy 3 MPV for the price of a Provari and not have battery decisions or charger decisions.
