Hi, I got a couple of these in last night. I immediately ignored the vertical coil suggestions and built them as horizontal .6 Ohm coils straddling the center divider with the coil at the height of the air holes. So far I'm pretty impressed. I'm finding great flavor and a nice warm vape at 17-18 Watts. I've run them from 15-20 Watts and I'm finding they're very sensitive to the power. 15 is a very cool vape while 20 is hot. Anyone else get these in so far? What kind of builds are you trying?
