I have nothing bad to say about the provari, for sure. I've gotten to use both the regular v2 with extension and the mini v2. they are very well built, they look nice, and they have a lot of good features.
I was a constant tube mod user until about a year ago. At one point, I owned somewhere between 25 and 30 tube mods. I used an assortment of attys, cartos, CE2 tanks, and carto tanks on them. Even though I generally enjoyed the vape, I always felt like CE2 tanks and carto tanks were a hassle. Punching cartos or modding E2s for tanks gets old. Filling and carrying cartos gets old. Carrying bottles of juice for dripping gets old. At the time, it was about the best I could do... or so I thought.
I'd read a lot about bottom feeders. As you can tell looking at this forum sub-section, there are lots and lots of satisfied REO users. I was intrigued by the idea of having an on board juice supply and an easy feed method. But, I was heavily invested in tube mods, tanks, cartos etc. So, I left the REO on my "want to try some day" list for quite a long time. -- I ended up buying a plastic bottom feeder for $25. - I was surprised. It worked really well. I used it more and more often and really enjoyed not having to carry much by way of supplies and not having to fill tanks or punch cartos etc etc etc. I used that little plastic feeder literally to death. -- The whole time I was using it, I knew I'd end up breaking it eventually and I kept hemming and hawing over the REOs I'd see in the classifieds and I'd check to see what colors were in or out of stock on REOs site.
Well, as expected, my plastic feeder died. I found a black and silver mini on REOs site that day and bought it. In the first month, my REO Mini had almost completely taken over as my primary vaping device. A lot of really nice tube mods in my collection just weren't getting used any more.... then I bought another feeder. Having two high quality feeders was a real pleasure and I just stopped using tanks entirely... Then the REO VV Woodville came out and I ended up owning three high quality feeders. I still drip my triple-v sometimes and I occasionally carry one of my rough stacks... but I am completely convinced I'll never buy another tube mod. Feeders perform just as well and are way easier in that you don't have to carry vaping supplies everywhere you go or have to fill tanks or punch cartos or modify E2s or fill cartos or carry bottles of juice (etc etc etc).
The first three things I look at for a new PV are 1) High quality atty connector (can't even tell you how many times a cheap connector has let me down) -- 2) Durable construction. -- and 3) Feeder. REO has mastered these three items. REOs have one of the two best atty connectors I've ever seen - they are more than noteworthy for the quality of the construction - and they have the best/easiest to use bottom feed system of any bottom fed PVs.
