This tire gauge is easy to use and provides consistent results. The rotating head eliminates the problem of hose twisting, and the small head size makes it easy to switch from motorcycle dual disc brakes to an air valve. The backlit digital display is easy to read in any ambient light. The battery level is fully visible as a clear bar graph on the front of the instrument each time the instrument is used. It's hard to find anything negative about this sensor. And the price was reasonable compared to the competition.
