This gauge seems to work well. I've only really used it a couple of times, but it seals the tire valve well and multiple readings on the same wheel are always the same, so it seems consistent. After using it to inflate all four tires to the recommended pressure, the car's pressure warning light dimmed, so that's proof I need the gauge to be accurate. You had to use one without) and the long hose allows you to close it tightly with one hand while taking measurements with the other. It also keeps the last reading until you press the release valve button - very nice. Overall the quality is good and the price is very reasonable. I hope this sensor lasts a long time so I am happy with my purchase. Fully recommended.
