UPDATE APRIL 2021 16 months and this thing won't hold any more pressure. Kept in my work lunch box along with snacks, charging cords, headset, flashlight, etc. This bag has been in the truck's cab most of the time and has received minimal abuse, but it's already behaving like I've hit a wall and broken something. In no case should such an expensive sensor fail in less than a year with normal use! UPDATE APRIL 2021 Tried to get my CD and had to get a sensor for my test. It was a bit more expensive than I expected, but I needed one that was over 120psi and strong enough to withstand workplace abuse, so it fit the bill. I have disqualified all digital meters with batteries because they are easily broken and fail over time. Ever since I got them, I use them at work, on my jeep and on my bike. All my life I've struggled to get the sensors to work, but I can say with confidence that the problem wasn't with me, it was with the instrument. This thing was relatively accurate on the 2nd, 3rd, and 4th readings (+/- 2psi maximum). The quality of the sensor itself is good, it seems that there is not a single cheap part in it. The glow in the dark is a nice touch, especially since I work at night, but the standard glow in the dark quality is so I'd recommend a light if possible. It's definitely a great tool, but as with most tools, always -1 star, made in China >:(
