Have you looked into the bottom feeder box bods? Combine the flavor of dripping with the convenience of a tank and you have a bottom feeder. The Reo even has a variable voltage model.
Doesn't Provari use a different system of delivering a constant voltage than most vv/vw devices?
The vw to me, sounded more like a gimmick - a useful one - designed to compensate for not having more expensive power regulation like the Provari already has. So why would Provape upgrade to VW if it doesn't offer anything more?
Now sub-ohm vaping might be different. Provape upgraded v1 to v2 to increase voltages and I wouldn't be surprised if they did something like that again.
I'm new here, not an engineer or electrician, that's just my understanding. Please correct me if I'm missing something. I've got no pride about learning.
