ATOTO AC-UTP1 USB TPMS Tire Pressure Monitoring Sensors

Installation was super easy. Instructions are provided in multiple languages and pretty straightforward. You can put the well-labeled sensors on in about 5 minutes and the USB receiver is plug and play. There are 4 little rubber washers in the package. Installing the sensors themselves are pretty easy too. Unscrew your current caps then screw these on. Each sensor is labeled with the predetermined placement that corresponds to its location in the software. This means when you get your tires rotated, you will need to move the sensors back to their correct locations.
