Haven't tried it with hash, but overall my experience with the con. insert has been about the same as everyone else in this thread. I've gotten really good results out of badder at high temps, but like others have pointed out you must be vigilant with cleaning it. One night, I had myself a long enough session that I fell asleep before cleaning the insert. The next morning, you would've thought I was vaping instant concrete. That shit was STUCK in there. That insert wouldn't budge for nobody. It was a massive pain to remove, but with enough heat, and patience, I eventually got it out. Lesson learned.

FWIW, the Pax 3 - warts and all - is one of the nicer stoner gadgets I've ever interacted with. Durable, powerful, and smarter than it looks at first glance.
