Back-lit display is easy to read, and the device fits in my hand. Contrary to what consumer reports, using it is very simple. It is very reliable and very well designed ergonomically.

The meter uses two cr2032 batteries, accessible by removing the one phillips screw in the rubber coated battery cover. It has a well placed spot for your thumb to push the gauge onto the valve stems of your tires. Although better than most stick gauge...  Read More

It has psi or bar readings. It just keeps giving me a reading of 50 psi. My only criticism is that when you use it with an inflator needle to determine the air pressure in a ball, you lose some air every time.

When it beeps, it resets itself and erases the reading it just took. It lets out too much air while you're trying to get a reading. This negates the convenience of having a digital gauge.

This tire gauge is completely inoperable in the cold- roughly around 15°f or below. This is a huge problem here in michigan where it sometimes stays below freezing for 2-3 months a year.

It is extremely difficult to make a sealed, air tight connection between gauge and tire stem. Loose fit over tire stems requires extra effort to get a reading. Great pressure gauge totally ruined by one thing, a bad seal.
