Well I picked up an MES 30 on Craigslist and today I was messing with it just to see what temp is displayed vs the temp on my maverick which reads 212 exactly in boiling water. I got some interesting results. Placed the temp probe roughly in the middle of the smoker and set the MES for 275. Here she is... This was very confusing to me as I thought the smoker only went to 275. Didn't think the MES thermostat would be that far off. Anyone else experience this? Thanks!
