Air flow needs a redesign a bigger charcoal pan with no holes in the bottom I will say it smokes ok for a little bit until the charcoal pan fills with ash then the holes on the bottom fill up with ash and the air adjustment on the bottom fills up with ash and the air flow is choked off and the fire goes out with everything wide open I do have a different brand with a similar design and work really well but I need a bigger one thought it would work well I was wrong I know Cuisinart I s a great product but not this particular item I am disappointed in this item
