IMO, I would still keep the ProVari, the longevity of the board hasn't proven itself yet..I hope it does, as you can buy 2 VMax's for the price of 1 Provari

..idk, def tempting..I'm not completly sold yet...but getting there
Well I am way out of warranty on my ProVari and I wonder what is in store for the future for ProVape. Once China can find a way to make a comparable product US makers have to face a few realities that simply come down to numbers on paper. If I do sell my ProVari I sign up for another 1 year full replacement warranty on the Vmax.
If I worked at a quarry, construction, warehouse, etc. I would never sell my ProVari simply due to it's almost milspec design. There are 4 things that there is just no getting around with the ProVari, the weight, the batteries, replacement value, and the inability to dial down voltage should you inadvertently click past your sweet spot.
Trust me, I thought I would be buried one day, my cold hand clinching my ProVari. But I have felt this way about many things in my life, the fact that my ProVari has gone unchallenged for 18 months in a world where new mods come out every other week is a testament to it's quality.
Just sharing....to each their own, the SS Vmax has impressed me beyond belief, these are both great mods in their own right.
My problems are that:
1. I need something that's portable and won't leak if I throw it in a pocket carrying case (I carry 4 vivi novas with me in a camera case currently.
2. I haven't had much success with carto tanks. Maybe it was just the Resurrectors I was using, but I didn't like the flavor of the tank filler.
3. I change flavors a lot, which is why I carry the selection of Vivi Novas
4. I travel around a lot, so dripping is out of the question, sadly.
Hillgiant....why not get some Ego Mega 4x Cartos....hold 4-5mls, no leaks, will work on your Vmax, pretty affordable. The polyfill might be an issue for you though.
