Provari. Main 2 factors deciding me on the Provari, beside the usually ya ya, build, quality made in USA..... is the fact that when you have dialed in the voltage for your sweet spot on the juice you are vapping, that voltage is set in stone, it never wavers from that setting through out the charge of the battery, change out your battery, and it is still set at that voltage. The other sell point for me was the 16 second cut off for a single vape. Most every other mod, ego, cig-a-like, has a ten second cut off. I still haven't experienced the 16 second cut off on my Provari, have tried but way to much vape. On an ego style battery or other device, when you push the button and wait the 2-3 seconds for the coil to heat up and start vapping, you then only have a 7 or 8 second vape time. With the Provari you have an very effective 12 to 13 seconds of vape. Yeah that's a really big difference IMHO. Was always experiencing shut of on my egos and cig-a-likes,
And as variable anything, we all have to admit, depending on the juice we are vapping, that when you change to another flavor, you have to dial it in again. So the set it and forget it just doesn't come out in the wash/debate, that is if you are like me and try to find the best flavor and vape of your juice.
I do recommend the Provari if you are looking to upgrade from an ego. Why Dic around wasting time and frustration. I did, I'm a newbie, only been vapping just under 5 months, and am glad I have a Provari and not something else. Would have bought a VTR, if they were available, may end up getting one in the future, but will try to talk myself out of it. It was hard and still is, not to get in on the pre-buy offer.
