I like my ProVaris for one reason only. Accuset technology. Whatever number I set is what I get. Seems obvious, but currently, I haven't found any Chinese offerings that can match it. If you have found one, please share (charts/readings help). I have been looking for a friend who's looking to upgrade from the eGo twist. He doesn't see
vaping as something to spend alot of money on. I want to recommend something that I'd personally use, and so far I haven't found a cheaper alternative that does what the ProVari does (Accurate readings only, I don't expect longevity out of a cheaper
device, everything breaks eventually). Right now, there's nothing in between it seems to me.
