Yeah, I've heard about the heater changes.... the older Extreme models would heat to 350C I believe, but the one I bought only heats to 250C, which seems to be perfect. At 250 I'm not burning the "herb" and when it's done I get the infamous burnt popcorn smell, so I believe it's working perfectly.

This thing is pretty damn awesome too. Not a purchase I regret. I think my favorite way to inhale is balloons, even if it's not the most potent. I like whip shooters too, the Extreme is awesome.
