Let me clear some stuff up, I agree with retired, this ...... contest crap is stupid.
I don't hate the Provari, I loved mine so much I owned 4, I defended the Provari against people who made similar ignorent comments, like the menu system, or my personal fav, "if I spent that much money on something I wouldnt want to take it out of the house", people who make these statements are usually people who have never owned a provari, thus making a declaration based on ignorance.
I could give you pros on behalf of the Provari, plenty, its in my opinion the 3rd best device out there, I even prefer it to a kicked mod. If I were to buy another tube mod it would be a provari.
All that said, I hate charging batteries, I hate having to pull out a charger, multimeter, and all that, so, at one time I had nearly 30 batteries, all in the interest of charging once every 2 weeks.
The Darwin, and the Opus won for me, on that alone, never mind the ease of VW over and against VV, its the fact that
I can vape til my eyes bleed on my opus and I'm good
And that's 1200 mah, never mind the Darwin's 1800 mah, both of which, depending on use get charged everyday, along with my cell phone at night when i go to bed. 1 battery will not get you a full day in a Provari.
Any other flameworthy comments will be ignored, so if you want to troll go troll in one of the TW threads.
I think it is also pertenant to point out, the OP asked this in the Darwin forum, the question itself begs that he is looking for an honest comparison, which can only be done by those who have used both.
