I agree with Edge. When I cook a load (12-16) boston butts on my FEC, I put them in the night before and go to sleep. I will say that I do use a Maverick ET-73 remote theremometer which has the capability to monitor a smoker within a set range of temps and sounding an alarm if it goes outside that range. No smoker is ever 100% perfect. But I feel very comfortable the FEC. One of my teammates uses a Cookshack at home and swears by it.
