Well I did test it out last night.
Over all it worked well and will be a great backup or hanging around the house setup.
The "timing" of how long I hold down the button is a little different from my ego twist. It seemed to be happy when you held down the button for a extra second or two before inhaling. I have no way to check the voltages, but if I cranked it up it defiantly was putting out more volts.
It also worked very well for dry burning an atomizer I was cleaning. I liked that I did not have to worry about how much battery I was using.
My only other comment would be that it is very small. So small it can be hard to hold & push the button. I think I will try and fashion some type of handle or holder for it and add a USB extension.
For the price I am VERY happy with it. I love the idea that if I forgot to charge my batteries I can still vap.
