The advantage of using a PID is that it will hold set temp precisely,this is a must when smoking certain foods like sausage.A stock MES has large temp swings by design,it cycles the element on and off to burn chips in the chip tray. Most ditch the chip tray and use an Amazen tray or tube that will burn pellets or dust,this can provide up to ten hours of smoke and eliminates the need to load chips every half hour. The mailbox mod eliminates the need to ever open the door to the smoker. I personally don't use the mailbox,I use a ubolt modified tube with dust and place it on the bottom left of the smoker.What advantages do you get by hooking up an Auber PID controller to your MES, and modifying the MES40 by linking the power cord straight to the element? Additionally, why is it advised to maintain the mailbox? Furthermore, how does the decision between MES30 and MES40 impact this advice?
Just asking because I am planning to buy one. Could you please give me some advice, as a big brother?
The advice applies equally to the 30 or 40.
