Bests & Worsts Reviews from Amazon

This was one of the cheaper dial pressure gauges available but it was accurate right of the box. It matched a digital gauge I have, and then after my car dealer did a scheduled maintenance including tire pressure check, this gauge showed the tires were spot on the factory recommended PSI. So I assume their gauge and this one are right. Having 3 wrong by the same exact error seems unlikely. It is easy to get it sealed against the tire valve so that you can get it to read without having air leak the whole time. Also, there is a valve that keeps the pressure so you can take it off the valve and read it. Then just push the little button on the stem to let the dial go back to zero. The one thing I would change about it is the angle of the tip. While rotating the tip does allow getting to a valve stem from about any angle, I would prefer a straighter connection. That's not a big deal as all it would do is allow me to take pressures a tiny bit quicker. My old dial gauge had a straight connection and I never had any problems reading no matter where the stem ended up.
