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

These are great everyone should have one

Only 4 caps were in the bag that was identified as a set of 8 (which is what was purchased). I requested a replacement set since I was missing 4 caps. The replacement set had exactly the same issue, bag labeled as containing "Qty 8", but only included qty 4 caps. When the set was installed, one of those 4 caps was leaking through the cap and coming out at the clear plastic to steel interface. Would definitely not order again. Value for money:Had the product contained qty 8 pieces (that performed as advertised and did not leak) at the price listed, it would have been a good value, but as outlined above, it was definitely not a good value. 1 of the 4 valves leaked (gross leak, 40psi to 10 psi in ~12 hr overnight on a size 235/55R18 tire).

Made my tires lose air

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.

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

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
