From the Puffco website... "The Puffco 3D Chamber is an innovative breakthrough in heating technology. Embedded with heating tracers in the ceramic bowl, the oil vaporizes on the side walls instead of the bottom only when inhaling to preserve the quality of the oil. This creates a consistently smooth hit while amplifying the flavor.
*Note: App download with firmware updates are required to use the 3D Chamber. Compatible with the Peak Pro only."
