Ok, I have other vaporizers in my signature, but none are as reliable and as good as my Pax. I use less. I use about .2grams in a load, and I do about 1 - 1.5grams a day. I used to be a 2 - 3 gram a day smoker. The Pax has been my daily driver for over a month now. I would classify myself as heavy. It definitely satisfies, and medicates which is exactly what I need. I love it.
