Review on 📏 HiLetgo 2pcs 0.56 inch Digital Voltmeter Ammeter - DC 100V 10A Amp Voltage Current Meter Tester, 3 Bits Blue + Red Dual LED Display Panel with Connect Wires by Dorian Bharadwaj

Have both. They arrived in static safe packaging but I'm a little disappointed in the lack of wiring instructions because they have more woman than the voltmeter display I'm replacing. My previous one only had 2 wires to connect, they have 2 sets of wires, 1 set of 3 (red, black and yellow) and the 2nd set I was expecting (regular red and black). The way you combine it with red and black makes your finger stand out really well. After returning to my wife I bought it and finally found the schematic but I can't even use it. There is nothing in there to tell me the product should be under load all the time (that's what the person who tested it for me explained to me so I don't get fired again) I'm sure it's more experienced people Anyone out there who would do this automatically knows where all the wires go, but I'm not like that and I wanted to change my solar system from the current "normal" digital voltmeter reading to "this" upgraded voltmeter and ammeter reading. To me this is a waste of my money and again I'm looking for something that doesn't have flimsy wiring or under reading load and most importantly should be properly connected (black/negative and red/pos+).
