The Pax 3 remains a smart and sleek handheld vaporizer. The newest design has made improvements to nearly every aspect of the build. Pax has been the premier vape for years and are still making a great herbal vaporizer. This model is about the same size as the previous but employs a battery powerful enough to heat the oven twice as fast as before. A better battery means less time spent waiting, and more time enjoying a stronger, more flavorful vapor.
