Thanks Sonics420. I found the flavour started to give off a popcorn-like taste at around the 7th hit but i was trying to see how much i could get off one bowl. When i looked at it when it was done it was uniformly dark brown. Medical Mark- The body gets warm but it never got 'hot' so that i couldnt hold it. Most of the heat was where the core is screwed in. The actual tip of the mouthpiece never got too hot for me at the end of my bowl. As for charge times, 2 out of the 3 batteries were fully charged, the other one was fully charged in half hour. I have not gone so far as to drain a battery completely yet. I'm changing batteries in between bowls and topping them off on the charger. I get a little OCD with new toys.
