I've tried all sorts of other gauges but at best they work 'well' to give reference values and not actual readings. very accurate and can repeat the same measurement consistently to within 0.1psi. The soft tubing/hose is also a plus as it doesn't harden in cold weather like some cheaper gauges do. The valve opening is easily adjusted to the valve stem without leakage. Hard case (box) pleasant to the touch. I like everything about it.
