Hey everyone, kind of new here. I have a MB 40inch xl propane smoker. I need the door thermometer. I have already bought one from MB and it was very expensive but I broke it. I went to Home Depot and bought a universal one, it reads 50-75 degrees off because it is too short. Can someone please lead me in the direction of a thermometer that doesn't cost 20 dollars, and has a long enough stem please? I have been looking at Amazon just don't know who to trust. And yes I do use TWO oven thermometers inside already to double check the IT. Thanks. Would this work????
