I had that same smoker in the 2D model. The only difficult (impossible) thing to control was humidity with the tiny hole at the top. Meat, fish, chicken turned out awesome, smoking to dehydrate certain foods, jerky, chipotle chilis, etc didn't work like something like the NuVu but the price is hard to beat for what you get.
I found it on OfferUp for $80. Couldn't pass that up.
Pulled beef came out great, just enough smoke with only about 3 oz. of wood used.
