I use my 732 with every cook that involves a large hunk of meat. I back that up with the installed gauges and have learned what they read in reference to the Maverick, so if the Maverick fails (it hasn't yet in 2 years) I can know where my cook is. I don't rely on the Maverick to tell when the meat (brisket, etc) is done, as I use the probe test, or bend test to determine when the meat is ready.
The Maverick gives me a lot of information about my cook without opening up the lid on my UDS to physically check. (This means more sleep or freedom to do other things while smoking.) Best accessory for my Q that I have bought.
