It's a crappy late night picture, but I bought this UDS off a guy that does competitions. After I bought it, I hooked up a remote Maverick ET-732 wireless remote thermometer. That worked well, but now I also have an Pitmaster iQue temperature controller. This combo is da bomb. When I first did a pork shoulder on the UDS without the Maverick and iQue, I had to go out and check it every so often and tweak the air inlets. Now, I put on the shoulder(s) and go to sleep while the iQue and Maverick are doing all the work and I sleep like a baby. I did the last smoke for 18 hours and didn't have to touch anything. Awesome!!!!!
