Avery good question.
the kitchen developed a light cherry wood aroma, more like the aroma from a very mild candle.
no smoke. there is a button , maybe you tap it , rather than push , that clears the smoke out of the chamber
before you open the door if you like. I just opened the door maybe three times, there was of course smoke in the chamber
but it was not heavy. Id say if the unit is used as designed , the aroma would be no more than a very lightly scented candle.
I liked the effect. with hickory , which I happen to have in a pure form , 40 lbs , maybe a bit more aroma.
but its not smoky in any way,
