I love Provari. A couple things though.
There is nothing wrong with "higher powered
devices". I look at them in terms of battery life. One battery mods last me two days between charges, two battery mods last four days.
Not bad, and I'm a bit lazy... lol.YMMV.
So, then there is hand feel... if you like smaller mods in general, the one which has the hand feel most like the provari is the JAC 75 watt mod. People like that and is what many provari users went to.
There is also the Dani extreme 3, good build quality but those are a bit complicated..up to you on that but there isn't the simplicity that is provari.
Then there is the American made double barrel by squid industries.. simple, excellent build quality, American made. Win win. Not the same hand feel though..
Good luck.
