Looks like a great temperature gauge!
Seems to be OK on first cook. For $12 what could go wrong? It is slow to get to there but I've got time. Supposed to be water proof but says don't put in dishwasher. Only seal is around the glass on top, otherwise one piece. With a max of 600* it should be useful when I need to know surface temp. Nice to be able to move it around or remove when desired. Just use my tongs. Disclaimer: I admit that a good chef adjusts technique to get to the best possible result no matter if grill temps are not desirable. But the whole idea of PID controls is Set it and forget it, even tho that is not always the result! Onward and upward!
