Review on 💪 Uharbour Pressure Connector Protector - 0 to 200 Psi by Luis Tuazon

Overall good product; tests accuracy against other gauges, fairly easy to read and quick to update. However, it appears to allow for very slow leakage. I have two of these (i.e. sample size two, not just one gauge) mounted on quick disconnects so I can place them anywhere in my air systems. If I leave one of these on my tank, it loses pressure over time (a few pounds per square inch per day in a 20 gallon tank); In contrast, if either of my two analog gauges mounted on the same quick disconnects are connected to the same port, the pressure in the tank will be maintained indefinitely. Analog gauges are also always instantaneous as they require a button press to turn them on, so they do not replace an analog gauge to monitor tank pressure. Unless you use them in a static pressure system. then they seem to be a good product.
