I'm curious as to why people own multiple versions of the same unit (v2.5, mini, etc)?
It's a sickness.. It's an addiction..
Dude, we're talking about ProVarii!

And there will be no back-ups, here.. Mine will be seeing equal vape time (after I finish putting "Big Yoda" through a vigorous break-in period, of course..
Now if you'll excuse me, I must continue stockpiling for the eventual regulatory & taxation vapocalypse..
Gonna have me a bunker full of ProVarii!
