Simply unbelievable.   The kitchen smells like BBQ but there is not one puff of smoke outside this machine.   And it smokes great!!!   The machine is easy to use and has presets for those who are experienced.   If you make a change (temp, time, smoke, etc) it will remember it for the next time (yes, you can reset if you need to).   When it is done cooking, the temp drops and it goes into warm mode.  No more waking up in the middle of the night to time the cooking right.   I could not be happier
