I am not a fan boy. I am aware that there are many choices that exist, and that the ProVari has it's limits. No variable wattage (so what? A sweet spot is a sweet spot, and whether it is 4.7 volts or 8 watts, the end result is the same - a tasty vape), no oled screen (would be nice, but whatever), can't fire sub ohm coils (really not a big deal since I am not a sport-vaper and i vape happily with my 3ohm sr carto), and it is on the pricy side. However, I bought my mini over a year ago, and i have used it heavily every day since it was delivered to me, and i have not had one single issue with it. If I did have a problem with it, I can get it fixed, warranty or not. It will last a lifetime and then some. Is it the most powerful and advanced pv on the market? Probably not. However, it is the one pv i can count on day in and day out. We'll worth the investment, especially considering that it works just as well today as it did before all the miles i put on it.
