I have decided to buy the standard with the extension cap for a couple reasons,,,,,,,
1) I can kill an MVP v2.0 in six hours. that's 2600 mah. I vape a lot,,,,,,,,,,and I honestly can't even IMAGINE even bothering with any battery less than a 490. I'd probably prefer a 650.
2) I've held all of them, and I just really like the standard,,,,,,,,it fits well in my hands (I'm a girl, and I have average girl sized hands, not huge ones) and I liked the weight.
As far as the Provari being out of date,,,,,,,,some of us just want a quality vape that does what it's supposed to do and does it well, that can take a beating and still be in good working order in 2 years,,,,,,,,,,we don't WANT a bunch of fancy stuff,,,,,,,,we just want excellent quality. I have VW on my MVP and frankly,,,,,,,,,IMHO,,,it's superfluous.
