Review on VSTM TPMS: Solar Power Universal Wireless Car Alarm System with 4 External Sensors, Real-time Pressure & Temperature Alerts for Safe Driving by John Milligan

Simply screw the four gauges onto the valve stems, secure the display unit to the top of the dashboard with the double-sided tape provided and it's installed. Another thing is to set it up to read tire pressure. The instructions, written by a Chinese citizen who thinks he can speak English, were very confusing. After trial and error, I finally got pressure readings from all four sensors. They are accurate and show the same pressure as my Snap-On Gauge. The built-in solar panel works very well and fully charges the device.
