Lol, take it easy. I will ask this again - does the PTC appear to be built similar to the Tel-Tru guage? There is a 'teardown' of the Tel-Tru in this thread but I don't see one of the PTC to make a comparison. I will pay extra for quality. Another question - is the PTC that you have a 'certified temp guage' or would that not be one of the $45 dollar models?
