Very happy with the solid construction of the tool. It felt good in the hand and, as far as I can tell, accurately measured air pressure (unscientific opinion). If you don't hold the sensor a certain way, it will be difficult to read. For right-handed people, the reading is displayed upside down when the pressure gauge is on the tire valve. It's annoying. Also, when you use the manometer, the chuck collar will loosen and you will not be able to take a reading as a result. When I tightened the "ring" again, the sensor worked fine. It's annoying. Overall I like this sensor more than most other junk on the market. Recommend.
