Yes, I've vistied the forum too. The problem is that when you get done the charcoal is all burnt to ash, and the moat is full of fluid. I have yet to clean the thing without ending up with soot streaked hands!
I got a laugh out of the demo. Not entirely true, I'd like to know how many coals it takes to cook that roast they keep showing! Last time I tried to cook a bunch of chicken I ended up bringing it inside and finishing in the microwave. I certianly can't imagine stir-frying, it just doesn't get rocket-hot. It's more of a slow cooker. Maybe I'm just not using enough briquettes. Also, last time I tried the 'potatoes and onions in the moat' trick, I ended up with sooty half-cooked potatoes.
If anyone else really gets the hang of using it, send some tips my way!
