The Provari is a great product, but the others are catching up fast.
Just got an iTaste SVD and have owned a Provari before. The ability to use wattage or voltage, build quality, ability to use 18xxx batteries without having to buy an extension, and consistancy definately give the Provari a run for the money. And speaking of money... it's half less than half the price.
If you don't want to become the iPhone of vaping devices, you should realy step up your game.
~just sayin~
Differences between the iPhone and the Provari.
The iPhone doesn't have the build quality.
The iPhone is not made in the USA.
The Kool Aid drinkers on the Apple front are much much worse than any other camp in the world.
I am not a Provari fan, but to compare them to iPhones is offensive.
