The PAX 3 utilizes both lip and motion sensors keeping the oven hot only when you're actually vaping and shutting itself off when you're done. The LED pedals on the face tell you whether it’s heating up, ready to vape, the battery level, temperature and everything else you need to know.
PAX has released a smartphone app (available on iTunes and Google Play), allowing you to customize heating profiles, update firmware and even implement security on your PAX 3
PAX 3 Complete Kit comes with a Concentrate Insert allowing you to switch from herbs to concentrates whenever you like. Usually '2-in-1' vaporizers really only do either dry herb or extracts well, but PAX has done a great job at having both mediums vape great in the PAX 3.
