I'd recommend getting a 4 pack of crucibles and an extra mouthpiece or two with your herbalAire. I've stepped on a couple of crucibles and it's nice to have one loaded and ready to go, even though they cool off pretty fast. You'll also want to watch out for the herbalAire bags. They're a bit thicker than Volcano/Toppits bags and they won't burst if you leave them on too long and they overfill, but they will leak vapor when they're full (like a safety valve), so if you leave the room and lose track of time, you'll return to an empty bag.
