You need a new grill thermometer I have decided for the Maverick ET733 and so far very satisfied: When you first use in Pulled Pork it has done best work. Through the radio microphone I could incidentally make even the garden and was not only ridiculed why I squat 10 hours Grill ;-) Adjusting works quite simply, display even in the dark without any problems and the temperature was measured very precisely. Would also be willing to pay a few euros more, when the case could still be built stable.
