I set mine at 370 and leave it. It's the best range for max THC and minimum toxins. Are you using direct draw? That's not the best way to use this vape. You will get vapor that way, but the hits are small and thin because of the small airway in the moutpiece extension. If you're getting vapor but not the high you want, I'd say you'd be out of luck with any vape. You won't get much of the couchlock feeling with vapor. The vast majority of herbalAire buyers are very happy with it.
