Well built, robust and accurate transducer. I ended up buying this Astro, ARB, Longacre and a Joe's Racing gauge. I returned both ARB and Joe's Racing. ARB was made in China and is not accurate. Joe's Racing was buggy because every time you opened a valve to fill a tire, the gauge read full line pressure, binding the gauge and throwing it out of calibration. The only way to prevent this is to make sure the line pressure is below 60psi, which is impractical when attempting to inflate a tire. I kept Astro and Longacre. The Coilhose CH15 can be easily attached to the Astro hose.
