I cooked 2 Navel plates Thursday night. Started at 7pm and finished Friday at 11am. EX6 here the temp perfectly. I had bought a Thermoworks signals a few weeks ago and used it for the first time with this cook I did open the smoker a few times during the night to check on things. Plates came out perfect and average temp in the pit was 223.5. You can't get better than that. I forgot to snap another screenshot pic when the cook was done, but it was still at an average of 224. Awesome machine
