Either will offer you VV as well as VW.
The Evic is cool since you can upgrade the firmware it uses, but it's still not quite there yet.
The Vamo has a super simple menu, and is really accurate in RMS mode.
They have improved the spring because the first models were rather weak. The gunmetal finish doesn't hold up well so I wouldn't recommend that finish.
I bought a Vamo because it had great reviews, I wanted to try out VW, and it was super cheap. I love it and have another in Stainless steel on the way.
That's very interesting Underwhelmed,,,cuz I've been Vaping a Genesis atty on a custom but, it doesn't have VV or VW and I've decided I want it,,,I had narrowed my search down between the same two,,,so,, having heard your endorsement I think that settles it for me,,,on to the VAMO,,,
Thanks,
PS - Btw, I just got a new ceramic wick (from scubabatdan) and it's super,,,If ya haven't tried one,,think about doing so..
