Hey No Brag, what's your PV of choice? I may be waaaay behind the curve here, but I went from penstyle (think it was a 401) to kr808d-1 and have never looked back. I use Vapor4Life's XL auto batteries with their blank carts(both high and low resistance) and fill with my juice of choice. I get about 8 hrs of solid vaping on a single charge. Refilling cartos is a bit time consuming, but I really only have to do that every other day, as I always have 3 or 4 different flavors going at the same time
I've always been of the opinion, "if it ain't broke, don't fix it" ,kind of gal but after reading months worth of reviews on mods and other types of PV's, I'm beginning to wonder if I'm stuck in the dark ages and missin' the proverbial boat? Whatcha think?
