@roxynoodle , off the SXM, it weighs in at .30 ohms. I've run it as high as 60w with no dry hit but the vapor is too hot for me to do more than a few pulls at a time. It hums very well between 40-50w. Much easier to build than the quads for me. Just be careful to monitor your coil ohms to make sure your clear of the chimney section. Great flavor that is closer to my dripper than my previous builds.
