The guru or any other temp control device makes these things even more set it and forget it! We use ours all the time to run long cooks overnight so we don't have to get up every couple hours and check on them. We can dial in the temp that we want to maintain and there is a temp probe in the pit, when it starts to drop, the fan kicks on to blow air over the coals and increase the temp. The fan is the only source of air coming into the pit so it's very easy to maintain a set point.
