Well it's a great pv from everything I've heard, but it's no Darwin. The Darwin is by far the best pv IMO. The Darwin has the ability to control wattage as appose to just voltage. I can't afford either a Provari or Darwin, but I'd love to be an owner of either device.
I've had both the Provari and Darwin. Both are excellent, but saying the Darwin is the "best PV" is highly subjective. It is a wonderful device, don't get me wrong, but I sold mine and purchased another Provari. I like carto tanks. Can you use them on a Darwin... Yes, but it is no longer pocket friendly when you do. If I worked in an office or only used it at home, I would have kept it. But I don't work in an office, and my Provari goes everywhere with me safely tucked in my pocket or belt holster (if at work). For me and my lifestyle, the Provari is a better PV.
As far as the click button menu. Seriously, people, it's no big deal. It takes a second to change or check anything. You make it sound like you need an advanced degree in buttonpressology to work it. Simply not true.
Also in regards to the E2 error. I don't use LR DC carts. For my DC tanks, I use 2.5 ohm DC's. I have never gotten an E2. However, if you do use them and get an E2, just turn the voltage down, and boom! You're vaping again. It doesn't shut down, melt in your hand, explode, turn into dust, or any such nonsense.
It's silly all the crap the Provari is taking from people who don't have one, and heard bad things about it on the interwebs, or are lava tube fanboys.
In my never to be humble opinion, the quality of the build, features, and regulated voltage far outweighs any possibility of getting a possible error if I happened use a carto that was meant for low voltage PVs anyway.
Just my $0.02. [/rant off].
