8pcs Universal 32PSI Car Tire Pressure Monitor Valve Stem Caps Sensor Indicator, 3 Colors Alarm Tire Indicator

I went out today and one of my brand new tires were flat.... then I noticed that one of these caps came apart and allowed air to escape. It appears just the fact that the viewing window is under pressure, it blew it off, allowing the tire to deflate. I was lucky it happened in my driveway!! How dangerous is this?!

Bought last year. Everything was going OK, then one day i walked out and my tire was almost flat and the sensor was still in the green, tire had 6 lbs of air in it. Another broke off in the snow, which resulted in an instant flat. I tested them all on a low tire and none of them worked properly. I would not buy them again. Maybe a more expensive set might work, but I have decided the convenience of knowing my tire pressure at a glance was not worth the problems in the end.

Work great! Simple to install. Makes it obvious to tell which tire has low pressure.

Do not buy these. I bought them 12/2023 and have had them on the same car since. Within the last week, I have walked out to find 2 tires flat. No nails, holes, etc. The only thing I found were that these caps had the plastic break off and leaked all the air out. Only reason I'm leaving 2 stars is so they can't get this removed

So far good

Great product let you know if your tires are holding air. And accurate if your tires and good it'll be red or yellow if you're tired is holding air it'll be green I tested it so I know it's accurate but a good product great buy

Worked for my tires the fit doesn't screw all the way to the thread which wasn't expected but it still worked out.

They did not work for me was very disappointed. They just always showed all three colors when I made sure all my tires had enough air in them.
