Review on ⚡️ DROK DC 4.5-100V LED Voltage Current Display - Digital Voltmeter Ammeter Multimeter Panel for Automotive Motor Battery - 0-50A Volt Tester Meter Amp Detector - Voltage Amperage Monitor Gauge by Marty Orthodontics

I ordered two of these devices for my solar energy project. I have two 80 volt power supplies with a maximum current of about 10 amps. I built a special box and panel for two meters. The box is fairly tight and the wires feeding it are 8 gauge. I mounted it high up on the wall, two channels side by side. The first day worked great. The second day is not very good. The left display works half a year later. The right one didn't work except for the first day. I ordered old analog gauges to replace. I'm giving three stars because one still works.
