Review on HYDRO MASTER Pressure Gauge Large Motorcycle by Christopher Sullivan

I purchased (2) of these gauges because I liked the brass construction, 0-60psi for better resolution between marks and pivot points on the end of the hose and on the gauge. However, in less than a year(1) the gauge movement is slowly reaching full reading and is now reading as low as 4psi. I assume moisture/steam got into the sensor and ruined the mechanism? (It never resets, so it's not a problem). It's a shame, because I really liked the properties of these sensors.
