Malcam Bluetooth TPMS Wireless Tire Pressure Monitoring System,Mobile Phone Real-time Tire Pressure Monitor With 4 External Sensors

I mean the app has some things in Chinese but the whole point of it was to read my tire pressure and it did it’s job. I have some 18s on my car with streatched tires so this was so helpful

It let ALL of the air out of one of my tires and the others only updated in the app once. The app is also so underwhelming. Bad translations all over it and the design looks like a toy.

what are the chances of 4 dead batteries upon arrival? According to the app, 100 percent. And, very poor chinglish directions

Thrilled with this product. I purchase them in June and they read true. Using them on a Can-am spyder three wheeler road bike.
