With the PAX PLUS, it's easy. Simply grind your herb to a medium-coarse consistency and pack it tightly into the oven. Press and release the mouthpiece to turn on. Wait for the X to turn on, then draw gently to produce the vapor and enjoy. To use concentrates, place concentrate within the center circle of the Concentrate Insert, close the lid, and place the Concentrate Insert into the oven. Once powered on, set the Experience Mode to Boost (4 petals).
