Review on 🚗 MNJ Motor LED Digital Dual Voltmeter - Round Panel Voltage Monitor Gauge Tester for Car Pickup RV Truck Dual Battery Pack, Blue by Phillip Samuel

Installation on my boat was easy, was very neat and looked great, perfectly level. It's hard to see in the sun but otherwise it's nice and bright. Everything worked fine until the water got on the device, like any other device installed on the boat, on the center console. Once water hit the unit the AUX side read 20+ volts on a 12 volt marine application. Other instruments on the AUX side started resetting randomly as they seemed to be receiving more voltage than their allowable range. It appears that this device is NOT WATER RESISTANT OR IP64 WATER RESISTANT.
