I watched several YouTube videos that rated digital air pressure gauges and I chose this one based on those recommendations. However my experience with this was the readings were wildly inaccurate as soon as you moved the gauge from the Presta Valve you lost the reading so you had to hold it there and while you held it there it leaks regardless of whether you pushed the release button. There are several other issues that I really won't go into now but this went into the garbage about 20 minutes after I tried it on my road bike and on my daily cruiser. My old floor pump is more accurate.
