For the people with the smokeware SS cap. I just broke the ceramic dome cap today as it fell off the egg. Does this item actually shut down the egg completely? How do you guys feel about it? Is it easy to control temps for low and slows and also for hot grilling? Was the learning curve easy compared to the daisy wheel? Any input would be great. Since my cap broke maybe I can ask my wife for the smokeware cap for my birthday next month. Thanks guys.
