I love my Guru, my WSM is like an oven the temps are rock solid. In the pic below the holes are sealed with the thermal tape supplied with the Guru, worked fine until the damper worked loose cutting airflow. I'm now rockin' the electrical knockouts. My only regret with the Guru is not getting the Cyber Q which can run two pits.
