Review on B-Qtech TPMS 4 Sensors for Car SUV, Tire Pressure Monitoring System with Sound & Light Alert, Time & Temperature Display, Real-time Wireless TPMS Monitor 0-50psi(3.5bar) USB Power by Antonio Scisson

My initial admiration for this product turned to disappointment. Although installing the sensors is very easy and the screen is bright, this device does not output PSI readings. There is a bar graph, but when I switch to PSI I get a static "03" for all four gauges. Also, the front left sensor is faulty. Sometimes it shows us 0 when I start the car and it takes a while to be recognized and displayed. Overall the device is reasonably functional if you're comfortable with bar pressure, but measurement errors and lack of PSI readings make this fall short compared to other competing products. 3 stars.
