This is by far one of the best vaporizers I've ever used..... I would consider this the Apple version of vaporizers. Pax even has a weight to it, that makes you know that it's quality. The way you turn Pax on is by pushing the mouth piece in and it heats up in seconds being ready to use! You load the herb on the bottom of the device that has a magnetic cover. Its super easy to clean as well!!! I'd recommend grinding your weed up pretty well to achieve optimal rips. You will love this vaporizer to death.
