Barbecue Grill Thermometer BQ225, 2 inch dial and 2.13 inch stem

With all the great reviews out there, I must have got a bad one. It sticks at a temp lower than actual and then jumps up only after you tap the glass. It’s the same when going down as well. I hope my next one is more true to what people say. Sorry to be a downer but this was my initial experience. Update: I received my replacement gauge and it works perfectly. As I said, I guess I just got a bad one. Will buy again.
