I just received my DAV which I won in this contest today. I absolutely love this unit! I probably would never have tried a variable volt unit had I not won this one, and I would have been missing out for sure. I'm still experimenting with the settings, but I can tell you that I love the 3.8v setting with my 1.5dc carto! With my new awesome unit, I also received a hand-written note of congratulations from A.--a very nice touch.
Please let me express my heart-felt thanks to the kind folks at Vapor4Life for putting on this contest, and for introducing me to such an awesome unit!
I put my name to everything I say and do. The Buck Stops Here.
