Hey There, thanks for this question and it goes to the heart of why the Puffco Plus produces such exquisite flavor profiles. We use a Ceramic disc heater and no exposed metals in our heating element. Plus, the chamber is quite deep, and with our Puffco Dart embedded tool, your product hovers at the perfect distance from the bottom of the chamber, producing superior airflow. We hope you enjoy and please don’t hesitate to ask any other questions.
