Review on MICTUNING J0001L Waterproof 12V LED Voltmeter for Boat, Marine, Vehicle, Motorcycle, Truck, ATV, UTV, Car, Camper, Caravan - Red Digital Round Panel Display by Thasapon Keitt

I like this gauge, I installed it on the dash because my factory gauge is a dummy gauge and I needed actual readings. I noticed that the readings were low when my battery was on and my alternator was actually running when it was running. I checked the battery terminals with a voltmeter and you know what. It was right! I checked my battery and I'll quote a replacement haha so she did exactly what I wanted, she gave me accurate readings so I could monitor my electrical system in my truck and helped me troubleshoot a bad battery to diagnose. and it looks cute on my dashboard too. easy connection. I will buy more if needed.
