This version is high restriction, and needs additional airflow from the top for proper function.
Put your favorite bubble caps to work with these blenders specfically meant for extra air from the top! Or, if you prefer a high restriction nail, this is the one for you.
The Blender design has powerful centrifugal action so the walls of the dish become a primary work zone for vaporization. The whole spectrum of accessories comes into play with the Blender; spheres add heated mass and lower the work zone.
