ST Shengtuo 2.5-2.8bar/36-40 PSI Car Tire Pressure Monitor Valve Stem Caps Sensor Indicator Easy to Read 3 Color Eye Alert, Aluminum Alloy CNC Machining, Pack of 4

It not only monitors tire pressure in real time, but also displays the exact pressure value. Before every drive, I check the sensor to make sure my tires are in good condition. A few weeks ago, my tires were worn out due to low pressure, but fortunately this sensor reminded me in advance and inflated them in time to avoid a bigger problem. It is very easy to install and the performance is very stable. It is definitely worth every car owner.

The media could not be loaded. Very dissatisfied with this product in the center, it blew out which cause the release tire pressure causing it to go flat

Excelente calidad y funcionan perfecto

FYI It fits perfectly with my car -BMW

I am unsure why but it only will show the 10% below 36. At 75% below 36 it still shows yellow. But still helpful.

one of cap was defective

Were just as I ordered.

They leak and leave your tires flat When you wake up in the morning
