4pcs/Lot Tire Pressure Monitor Pressure Gauge Cap Sensor Indicator Alert Monitoring Tools Kit

On one gauge, the green color is not long enough and showing too much red when tire pressure is good, so it is confusing. The rest work ok but I expected they will show only red color when tire pressure is bad. It shows all 3 colors. UPDATE Some of them started to leak air. I thought the tire was punctured. Went to the service to repair the tires 3 times and paid for inspection in vain until the 4th time the mechanic noticed that these cause the tires to lose pressure. Removed and threw these in the garbage. Seemed a great idea but not really useful in reality.

As in the description. AFTER INSTALATION ON THE TYRES THE RESULT IS : 3 PCS. ARE OK, 1 PC. THE GREEN SLEEVE IS LOCKED INSIDE AND SHOWS WRONG RED AT NORMAL PRESSURE. I WILL CLAIM TO JOOM.

They work ver well on my car very clear what colour is seen had on for a while now very happy great seller great item UPDATE didn't change colour when tyre had puncture

Seems to be ok but not driven in a while, they do stick out a fair bit though, so concerned they will catch on the curb and they will snap off.
