Mike, while waiting for clnire to return, I can tell you that most of us have the SXK Doggy. There is also an SJMY version that a few have purchased and like. It has a slightly more open draw than the SXK, but can probably be adjusted down.Thanks @clnire ... did you get any specific one and where?
I have three of the SXK version and have two more on the way, all from fasttech. Great flavor. I build them anywhere from 1.0 to 1.5 ohms and vape most at 10w.
