The Pax 2 works really well with a "Pax Pusher," which is an aftermarket product. The Pax Pusher is a piece of metal with an adjustable screw that holds the dry material in place. This metal contraption allows an individual to pack up a half of the material chamber. Super nice. Allows an individual to use 0.1 of an herb and still receive the benefits of the herb. The Pax 2: One button. 3 different heat settings. Grind the material pretty finely. Break up material with fingers more finely. Load the material into the chamber. Make sure the chamber is packed somewhere in between loose and super dense. It needs some breathing room, yet need to be packed so all the material is touching other material. Insert Pax Pusher, if you have one. Cap it. Press the button. Wait 90 seconds or so until lights are flashing green. Draw in slowly. Say goodbye to smoke in the lungs and say hello to a healthier lifestyle.
