I'm also a ProVari user, but I'm vaping it constantly on 2.47 Amps (1.7 Ohm RBA on 4.2V).
So the eVic is totally useless for me, because it's impossible to get the same vapor out of it as I get from my ProVari any time.
I'm really disappointed with the eVic, because the upgradeable firmware is basically a very good idea and I really wanted to use it.
I wish I could upgrade my ProVari too. Adding new menu points to it would be dream.
I actually like the idea of the Puff Counter. Not because I'm counting my puffs, but because it's a very useful counting system to measure the exact capacity of your battery. (or to compare two batteries to each other)
Counting the vaping time in hours is meaningless, because sometimes you vape more or vape less.
But the puff counter is an accurate way of measuring the true vaping time.
Guess I'm not a hard-core user, so I like the evic... looking forward to to new functionality when it becomes available. I'm not concerned by some of the issues reported. Bottom line for me is it's a cool device that has features no other device on the market has. I like that since I like playing around with gadgets. It also vapes just as good as my provari mini as far as I can tell. Looking forward to being able to vary the wattage within a single puff, as I think having that feature may very well increase vape quality.
