I've been using my pax for a year....
.... I've never gotten smoke out of my pax, even with the driest herb and the hottest setting. I keep it clean so if you are getting actual smoke, u may have an issue with the unit... Or maybe it's not clean?
I have the pax 2, I managed to get smoke after a little while. Grind fine, fill up the container, padck well, but not too much (air needs to go through).
I do not know why it does not happen at the begining...not enough weed may be. Mine is not dirty, but it is not super clean neither. (I did not use the alcohol to clean it, only the little sticks that came with it (which are annoying because they leave fibers inside the tubes, and so they may be vaporized too!).
But I think it is the maount of weed, how fine it is, how it is packed. Not very complicated though. Now i get vapor each time.
I still have to get high with it though. Taste is great, but well, effect is totally absent. the herb is vaporized though...
I would use it only if I have enormous quantities of weed so I can waste a little in the Pax2 for the pleasure of a good and soft taste.
In the pax 2, there are 4 temeprature for vaporizing. The highest can be slightly harsh, while the third, is just too soft. There should be something in between in my opinion.
I will try to sell it and get something else that would make me high. I don't know now, all those vaporizers look suspect to me now, like all the reviews videos I watched before making the purchase.
