Tired of the Masterbuilt Digital Electric Smoker Problems

I guess I am one of the lucky ones too. I have the basic digital model. I added the "mailbox", a separate temperature probe with the cord going through the top vent, and a dryer vent hose from the top vent to the outside of my shop. A baby monitor sits on the top. I set it and go. When the temp probe says it is ready, I hear the alarm in the house on the baby monitor. My smoker stays in my shop and has never given me any problem
