,,it's going to get some getting used to.I think the problem is that the chimney is relatively short... not much space between the coil head and bottom of the mouthpiece. The result is a much warmer - i would say hotter - vape than I am used too. I have a Kanger Geni Mini and even on that small tank there's a longer distance between coil and mouth piece. On the 1.2 ohm coil I have to keep the istick at 10 watts, 11 at most or else it's too warm for me. Sub-ohming will be a learning curve!
