Got to try'er out today. I'm going to try drilling more holes and getting a bit more airflow, if that doesn't do it, it's onto electric I go.... I could only maintain about 190, had 220 for 15 minutes once, and one time I got po-ed and added two handfulls of dry wood chips, then it hit 300 oops. But only lasted 5 minutes, then back to 190. So frustrating, 10 lbs of charcoal and 5 hours for some boneless skinless chicken breasts! I was doing better using my gas grill 'as a smoker'.
