U812 Autoreifen Druck Monitor System 4 External Sensor Solar Mini USB Verbindungsmodus
The monitor system needs a long time to "wake up " sensors (average is about 7 km of driving) . The communications between monitor and sensors is very delayed it is not real time as advertised. It happened once that sensor disconnected while driving and created alarm. One of the monitor functions "automatically on and off" is not working too. The display in the day light is difficult to read - it is surely not as bright as pictured on the website. Item arrived defective. I contacted BangGood Customer
