I picked up a pharaoh mini on a bit of a whim for a good deal and have been really surprised by how little airflow this tank has. It has significantly less airflow than my Kylin or Ammit Dual rta closed down one notch and less airflow than the OBS Engine Nano. I don't mind a restricted lung hit but I really expected at least a little more airflow. Has this been everyone else's experience as well? Does moving the positioning of the coil or removing the locking nut increase the air flow at all?
