I own a few mods, vamo, provari, innokin, the one I keep using all the time is innokin svd, it has vw, which the provari does now, I like using watts, it's the best output IMO, I do hope provari adds this to future upgrades, then the provari will be in my hand 24/7, I still think the innokin looks better, but it's not all about looks,the provari proforms great, but so does the svd, it's not lacking and smokes as good as the provari, inokin products are built great too, the innokin 134 is just outstanding, just picked one up, looks great and can be used as a weapon if need be lol, innokin would be my rec, u won't need anymore device than an svd, it is stellar
