High quality product but make sure it's exactly what you need. That is, it does NOT hold ANY reading after being disconnected from the bus. There is another model that does this, but it costs more. My car has a built-in Tire Pressure Monitoring System (TPMS) that uses sensors to show the pressure in each tire. On my old tires/sensors, the difference between the TPMS reading and this sensor was about 2psi. I recently changed tires and sensors and now the difference is 0-1 PSI. I trust this sensor.
