Review on Kinstecks Upgraded Version: Motorcycle Voltmeter 🏍️ DC 12V Digital Gauge LED Display - Blue by Fisseha Rodgers

I have a solar system so I have 3 different sensors to monitor the system. None of the three sensors show the same readings, but none of them are certified, so it's anyone's guess as to which ones are wrong; but everything is within 0.12 volts. The numbers are 5/8 inches, making this the only sensor I can read from across the room and even from outside the RV. I have a blue color that makes it easy to see or read. The wire exits the back of the meter and is easy to hide. The installation is very easy. All you have to do is connect the red wire to positive and the black wire to ground. Best sensor I've found for the price. Everything else was double the price.
