I'm on the fence with this, yes it's intriguing, and I've been sucked in by good advertising before, but,... I can't see how it can make a significant, or even any, difference. Charcoal will only get as hot as you can get air to it, Hot is hot, and goes up fine by itself.
I've cooked chicken in the 22 WSM directly over coals without the pan, like a drum does, with the vents open it gets very very hot, It's not going to get hotter with any device other then forcing the air with a blower. As for mixing the heat and smoke to eliminate cool spots, what cool spots? in a round drum like object everything "mixes" just fine, The only thing I can see is it's use as a drippings vaporizer, but chicken and ribs really don't drip that much to hurt anything. So.... someone convince me..lol
