12pcs Car tire Pressure Monitor Valve stem Cap Sensor Indicator, 2.4Bar 36PSI Pressure Monitor Tire Valve Stem Caps with 3-Color Eye Alert for Cars, Motorcycles, Bicycles.

Makes my life a little easier by instantly checking tire inflation without using a pressure gauge. Love it.

But, make sure that they are tight as they use the pressure to keep them reading but can leak.

Bought this product and installed them on my car tires. Not sure what happened but the top part where the green is broke off and the tire went flat.The top needs to be a lot more secure

They leak air...so technically they work since it indicated air low...but I had to keep going to get air.

Works well on my Toyota

The valve caps do not screw all the way down so it feels as if they will not keep screwed in. About a quarter of them slowly let the air out so make sure to listen when installing or they could leave you stranded.

Installed on 4 of my tires, had a low pressure warning on the dashboard the next at 9:00 AM before drive to work, found one of the tires 90% flat. Removed the tire pressure monitor and re-inflate the effect tire, took the tire to the Tire Kingdom’s get it check for the cause of air pressure lost, found nothing tire are good and only 2 years old, conclusion’s was the bad tire pressure monitor caps that cause the tire to deflates. So check your tire after installation and make sure it’s working properly. The other three tires is holding pressure well no leaks detected yet. Will check it again daily, do not want any more surprises when out anywhere.I revised the rating to 4 as it performed as expected, probably got one defective tire pressure monitor.
