That said 'Accuracy: +/- 2 psi', is slightly alarming. Mine is pretty old now and not quite the same design; it doesn't have the function of holding the pressure reading when removed from valve and nor the reset, air release value on the side.
I have a luxury metal item and a cheapo plastic one. The plastic one works better. Neither are currently available but both are over 10 years old and still work perfectly. I like the idea of analogue gauges but in practice I've always found reading them more difficult.
