Had one for a few weeks now used with the bottom feed pin.
It's really very good.
Easy to build with lots of build/airflow options. The flavour from it is great.
I prefer MTL and lower wattage but it could be a cloud monster if your that way inclined, it does get quite hot if your pushing much above 20 watts. So if you want low ohm/ quad coil etc. plan on getting a long drip tip.
Best for me is a single coil 1.2 Ohm diagonally over the squonk hole not too much cotton fed through and back across the deck on each side. Should make sense when you see it.
