Those old tire pressure gauges were confusing with the sliding extensions popping out of the gauge when the gauge was pressed over the tire valve at just the right angle. If not the right angle, then air would just escape.

With this tire gauge you no longer have to find the 'proper' way to hold the gauge as the shape of this device is automatically molded to the natural shape of your hand. Once over the valve, not only will the tire pressure gauge display the current tire pressure, it will also read out the measurement.
