Review on 🚗 IGYLAR Solar Power Car Tire Pressure Monitoring System: Real-time Pressure Read, 4 External Cap Sensors, 6 Alarm Modes - Easy Install, Reliable Car Pressure Monitor, 0~3.5Bar Range by Nathaniel Collins

If you buy this get ready to replace the CR1632 batteries in all 4 sensors when they arrive and probably every few months. I tried two new kits from OGYLAR and both had all 4 sensors with dead batteries. I have a Dlyfull universal battery tester which is great for diagnosing electronics problems. All batteries were completely dead and some were leaking. Either IGYLAR has had these sensors on the shelf for several years, or a defective batch of batteries occurred in the factory.
