Just got my mes 40 yesterday. I am currently curing the smoker using the maverick 732 therm. My question is how dependable are the mavericks? Per directions I am curing at 275. The Maverick is saying it is 290 and the built in meat therm in the mes is saying 289 but the box temp is saying 240. I would think with 2 therms showing the same temp that the mav is right on and the therm in the mes is off, but 40 deg?
