I have asked the same question. If I had the money, I would start with a Provari, then buy an eVic. That would be the safest way to find out for sure. Covering all bases, starting with #1.
You are forgetting Variable Wattage, something the current generation of Prothingy does not have. ...arguably outdated.
Evic=problems...
I've never had a VW device, so I can't speak from experience there. But I do know that, the way I vape at least, there is no particular advantage to having it, since when I'm in different moods, or switch RBAs, carto tanks or juice, I would want to tweak the settings anyway because the optimal V²/Ω doesn't always equal the same watts level.
So besides adding another layer of complexity to the menus, I don't see the point.
Since resistance changes with heat, wear and even gunk buildup it's not just VW... it's the fact that most devices with VW monitor the attachment for a resistance reading every time you fire it and automatically adjust voltage to maintain the same wattage. When I first got mine I was obsessed with checking the resistance of every attachment I put on it, especially if I thought I tasted a difference from one puff to a later one. I knew one of my disposable bridgeless atomizers was on the way out when it started tasting different and showed a change from 1.8 ohms (new) to 1.6 ohms (two weeks of use later) and 1.3 the day it died. On my stardust knockoffs a change up to .4 ohms is a good indication that it is time to give it a good vodka bath over night or simply replace the coil. The point is that if you chain vape a whole bunch of different attachments at different resistances it's nice to have a fairly accurate wattage to rule them all, something you can't do with strictly VV (unless you are checking them with a DMM every use). Sure, I still click up or down half a watt or two, usually for a different PG/VG ratio or a specific flavor, but that's what them buttons are for![]()
I think VW is AWESOME now that I have it too. I like to switch out my Vivi's/flavors throughout the day. Matter of fact, I keep my Segelei Zmax in VW mode exclusively. VW keeps me consistent, and if I want to, I can just bump it up or down. Zmax also retains VW setting when you swap out batteries. For some reason I find it resets VV. At least I think it does.
... I'll be most likely spending my vaping budget on adding a mechanical mod, juices, atomizers, drip tips, and that kind of stuff to my collection while vaping from my half-decent (actually quite decent IMHO) mid-range model LavaTube.
What exactly is un-user-friendly about a Provari?
