The Single Button menu put me off the Provari for some time, I was happy using my little 14500 VV Box Mod at work, but wanted something nicer when Out & About.
I decided to get a VAMO to check out the VW feature, the
device was decently built, had a variety of features for the price and turned a few heads because of the size. For me the VW feature wasn't set & forget, and I mainly used it in VV mode... so I sold it to a co-worker and finally got the Full Size Provari.
The One Button system is easy as pie, the device has a good weight to it and I basically like it very much, even though I prefer a Box Mod for pocket-ability reasons, this is more stylish. If I was to do it again, I would go with the Mini with Extension Cap/ 18500
batteries because I like the look of the Tear-Drops better.
Bottom Line, I'd recommend you give this a try and if you don't like it you could sell it. The other devices are so similar to the Vamo, they'd make a better replacement than
supplement for that device.
