Review on 🚗 Smart Car Tire Pressure Monitoring System - 6 Alarm Modes for Universal Vehicles - Wireless Solar & USB Charge - 4 External Cap Sensors Included - Real-Time Pressure & Temperature Alerts by Greg Roberts

Wanted to use it on my cargo trailer to keep an eye on the tires on long trips. Checked tires before putting gauges on, all 4 were at 64-65psi by other digital gauges as well as manually. It is displayed incorrectly on all 4 tires. Left it for a while, also thought they were going to be average or something but they didn't change. I later tried it on my truck and what he read didn't even come close to what the truck said or what I found when I checked them out. Unfortunately it is useless.
