Extremely accurate, ergonomic, does not have the external pointer stop to bend the pointer, and it is easy to read.  It does not hold pressure after the gauge is removed; the button on the side is for bleeding off pressure only. Purchase the rubber Moroso 89590 Tire Pressure Gauge Cover that is made for it, the protection and improved handling make it well worth the money and it looks much better with the cover on.When buying a tool it is best to get a good one that will last for years.  The research I did on the internet paid off, I am totally satisfied with this gauge.  Because it is a new style it can take a few times to get used to using it.  I recommend putting your index finger under the nozzle to make sure the gauge goes on straight to avoid unwanted leaking and apply pressure with your thumb, after using it a while this is may not be necessary.Being a mechanic I check my tire pressures on both vehicles once a week and accuracy and ease of use is very important to me. I keep this gauge inside the house to keep it nice and my old gauges in the vehicles.According to Moroso, each Moroso 89560 gauge is individually calibrated for accuracy within 2% which means that at 50 psi the gauge should be not lower than 49 or above 51 as it will not be off by more than 1 psi.The Moroso 89562 Pro Series Tire Pressure Gauge which is accurate within one half percent which means that the Pro gauge would be not lower than 49.75 or above 50.25 at 50 psi as it will not be off by more than one fourth psi.I had my Moroso 89560 gauge tested on digital calibration equipment and it was as accurate as the Pro is advertised to be through the range of 5 to 60. If you have a tire that loses more than 1 or 2 psi a month you can have a nail or other leak and several times I have found leaks by regular checks when one tire was lower than the other three.With high gas prices, keeping your tires properly inflated helps to get the best gas mileage, and twice I have been driving along and have seen people with low tires have blowouts which you can help to avoid by catching slow leaks early.The gauge is a great value and Amazon.com helped me to get the best price on a product I am totally satisfied with.  The one gauge I currently have developed a bent pointer from the zero external stop, the Moroso does not have the zero stop (it does have one where the 75 would be) and I wanted a nice gauge that would last and be easy to use so I am totally delighted and completely satisfied with the Moroso.
