Review on Alien 4x4 Tire Pressure Gauge 75 Psi - Accurate Heavy Duty Tire Gauge for Autos: Cars, Trucks, SUVs, Bikes by Marco Hubbard

Looks like a very well made gauge and doesn't require batteries like digital gauges. It reads the same pressure as the car's built-in TPMS and is easy to use when adding (or subtracting) air, unlike an on-board pressure that has to travel a mile or two before it gets an accurate reading. I never trust gas station sensors - some are good, some are not. One of the best things is that unlike a similar analog gauge I have, it easily seals the valve without putting in much effort to prevent air leakage during use.
