Just a side note: I got a provari mini kit and it came with a protank 2 (not the protank 1 listed). I popped it on with the 2.5 head that came with it and got no airflow at all...tried switching out the head (not one of the extras that come w/ it) and still no air/vape. Luckily I had another pro2 to try on it....whamo!, great vape. I tried to figure out the difference between the two, but could discern none. Guess I'll keep the wonky one around for spare parts
