Review on 🚗 High-Performance ESUPPORT Car 2" 52mm Digital Oil Temp Gauge with Red LED Light Temperature Meter - Enhanced Precision and Efficiency by Chris Shields

1 of 2 junk I ordered. Unfortunately they were for my boat and by the time I had them installed a month after I ordered them it was already too late. The reading is about 0.4 volts. Shows 13.0V or 13.1V when the batteries are at rest and fully charged, while my demand/load sensors in parallel show the true voltage at 12.6-12.7V. These sensors are basically inaccurate toys. The warning symbol is also always on. That's how they are designed. Cheesy. Save your money if you don't want an unnecessary toy scale.
