Review on 🚗 Tymate Tire Pressure Monitoring System with Large Colorful Screen and Advanced External Tmps Sensor - 4 Alarm Modes, Flexible Charging, and Easy Installation (0-87 psi) by Kevin Mariappan

Very small but large screen. We use it for our 23ft RV. It's too early to tell how well this works, but the initial setup works well. A few points to note: the power supply is a micro USB power supply and you cannot use the phone's USB charging cable to power it as it only supplies 5-9 volts. Use the included cover light cable. The transmitter on the bus only sends information while the vehicle is moving. After driving, it took about 30 seconds for the pressure to update. Sensors are supplied with water caps and a lock nut. Reads temperature, pressure and has high and low pressure monitoring. The monitor was originally located in the lower corner of the driver's side windshield, but the trailer's front right tire pressure did not change. I moved it over my rear view mirror and we had no problems during our 4 hour trip to the beach. UPDATE: The device stopped updating and after 1 hour the screen showed no tire pressure, only voltage. Sensors retrained, still no pressure. Came back for another block. Fingers crossed. To update. Email support and they were very responsive. I've tried the suggestions there, but there must be some interference preventing the device from communicating. They gave a full refund and let me keep the device! They provided details of another model suitable for longer trailers and ordered this unit. Excellent customer service!
