The Vivi works OK. I don't think I like it as much as pbusardo did on youtube. If I use up 1 mil in it, it will dry out and it is difficult to re-wick. As long as I keep it topped off it works great, but it's a hassle. It is like having a carto that always needs to be topped off. I tend to vape like I used to smoke. Vape, vape, vape, vape......wait a while, vape, vape, etc. So, a few hits in a row, it wont keep up. After it sits a while it's OK. My wife has started using it and at her pace it seems to be working well. She just "sips" it all the time.
As for 100% VG, yes it worked OK, but I got the same issues above with both VG and a mix. I believe MadVapes KickA$$Carmel is 100% VG, and I used that a lot in the Vivi.
Atty heads lasted me about two weeks or so before I felt I needed to try another head. The replacement heads I ordered (1.8) don't seem to taste as good as the original, but they are still working.
When I used it, it was on the Provari and anything over 4V with the 1.8 would burn (as expected). I currently have it on my bolt now that the wife is using it. It's fine on there. (sometimes I sneak a puff, cuz I like her juice).
Now that I think about it, at my wife's slow pace, I haven't replaced the second head in a very long while...I would guess at least a month.
I just ordered the Smok Tech version, we'll see how that works next.
