coolone1 --
I'm a fairly new vaper -- 9.5 months. I started on the eGo . Great device; I'll always appreciate how it helped me kick butts. I ended up buying a 3.7 mod. Once again, great device, excellent machining and worked as it was designed. But something was always lacking -- I tried different attys... and on and on.
Enter the ProVari. There's many modders who posted in the BIG ProVari thread -- they love it. There's at least one electrical engineer -- jimho -- who got the beta ProVari -- he loves it. Check out his posts. There's many long time vapers who love it.
What the other posters said and : it's well machined, sturdy,and backed by a reputable company .
I have no regrets about buying a ProVari. I can adjust my voltage in .1 increments to get the perfect vape -- and the power is regulated so it stays the same until cut off.
I'm still looking for a good , long lasting atomizer. But my search for a PV ended with the ProVari.
Buy one -- it's worth every penny.

Included is an index of sorts for the big ProVari thread that I used to help me decide.
