I have just purchased and used my Masterbuilt smoker with the digi temp controller - seemed to work really well (Ribs and Chicken turned out great)only problem was it didn't have that much of a smoke flavor? I used Hickory chips soaked in water and tried to keep it full so smoke was flowing out of the vent on top the most of the time.
could it be that I had the vent too open on top?
