Really smooth adjustable airflow and lots of room for coil configurations including single, dual and vertical. A PMMA plastic cap (stays a lot cooler than metal) and beauty ring are also included (with no AF control) and it has just about perfect slightly restricted MTL pull, so good. Squonk pin also included with xtra flat and allen post screws. A great value ($32) and good flavor for a standard height 22mm atty. I purchased mine at #Eccigity in HI as they are almost always first to get stuff from Asia as they are closer than we are. Pictured here is the PMMA cap atop the Pulse BF Box Mod by Vandy Vape. The two coils you get are ohm’ing in at 0.34, so just about right.
