It's here! Tore open the box, put on the 1.25 ohm dual coil carto that I had on my P16, and hit the button. Very nice, cranked it all the way up to 12.7 (Darwin was reading 4.2V, 3.1A, 1.3Ω), and even better. Time to start pulling out my old atomizers, I've got some 1.5Ω BE112's I'm dying to try...
