Mine came in yesterday. First vape was WOW! The juices I used on my eGo 1000mah batts were pretty good, but at 4.2v I have NEW juices from the old bottle. The flavor from a 3 ohm carto is impressive and the vapor is huge.
For two years I've been still smoking 8 or ten cigarettes a day while vaping. Since this thing came in I haven't wanted one or even felt the need to smoke and vape. Even after a meal I just vape the Provari and feel satisfaction. I'm done with analogs.
I know that vaping goodness is just a combination of voltage, resistance, a good carto, good juice, and the ability of the battery to supply consistent voltage at load. Variable voltage is variable voltage and my box mod will provide that, but this mod is so well built and designed that I'm impressed by the workmanship and quality that went into the concept. Eventually, I will get my money back from the $10 or $12 I save every time I have to buy a battery. Yes, that will take years, but I think this thing will easily last through the amortization period. During that time, I will enjoy every minute of the experience.
