the epower has been hands down a much better pv than anything else i have ever had. the batteries have held up several months so far and thats fairly heavy vaping. the switch i have is still the original switch, although i have a spare in my ecig parts bin i have not had to use it so far. the only thing i have had to buy since owning this thing is the carts, atomizers, and juice. it is extremely reliable. most of the problems i had with cheaper ecigs were the batteries. the batteries on nearly all units that have the switch built into the battery are trash, good luck in getting much more than a month or maybe two at the most out of those batteries.
the provari, my wife has one and that thing is purely awesome although its a little large and heavy for me to want to carry it at work. i love being able to adjust the voltage with minimal hassle on the fly. im very happy with its performance, although as i said its large, heavy and expensive.
