Just got the 1150 last week. Waiting on my new controller in the mail. I was dying to use the smoker so I did a 12lb brisket. It was not ideal trying to “smoke” it at 300 but it would not hold 250 to save its life so 300 is what I had to do. The bottom did burn in spots pretty bad. I did have it centered so it was over the “searer” with the vents closed. It actually came out pretty good and I must say I was impressed with the smoke ring. Comparable if not better than my offset smoker. Really looking forward to the new controller. I really want to smoke low and slow and not worry about the temp. That’s why I bought this monster. I enjoy my stick burner but I also enjoy being able to leave the smoker and do other work around the house. I also got the ERR message but I believe that was from my cap being screwed down to low. It was 35 and windy here so I didn’t want to open it all the way.
