The Mighty Vaporizer operates on a heating method which can reach greater than 375°F, the temperature required to effectively vaporize plant material. As a result, the produced vapor can be uncomfortably hot. The Mighty Cooling Unit prevents an unpleasant hot and dry vape. The cooling unit features innovative venting as well as a mouthpiece designed of heat-resistant plastics. These features allow the unit to cool down the vapor before you inhale. This set of three will allow you to have a clean cooling unit for each of your vaping sessions.
