I haven't even received my PID #2 yet, but let me tell you about temperature swings.... My Pit Boss Vertical smoker when set to 225 degrees would swing from 165 to 315 degrees! I don't care what the "average" of that is/was, that's not what I signed up for. After two weeks, I returned it. Give me; electricity, gas, or off-set wood/charcoal.
