These gauges are very cheap. I wasn't expecting a quality instrument to be installed at this price point, but these sensors were just awful.1. The needles got stuck from time to time and it took a few hits before they moved freely again. The sensor housing is made of very thin metal. When the lens caps were screwed in after calibration, they flexed enough that the arrows moved away from zero.3. They require constant recalibration.4. Temperatures are in Celsius, not Fahrenheit. Very disappointed. Obviously, Robinair isn't the brand it used to be. Such a shame.
