I have one. They work well and as advertised. Somewhat light on the smoke flavor but if you want decent smoked food cooked faster it'll do it. I liken it to a Cajun microwave.
Don't waste lump charcoal on it. In fact, I just use the pre-fueled stuff.
I've not used mine in awhile. I think it's at my Dad's.
