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 Michael Kosack

The numbers are nice and bright (especially with the dedicated 30V supply which you really should do if you need to work below 4V). Unfortunately, the two separate gauges show 1.32A and 1.28A in both, for a measured load of 1.00A. That's about as little as I can adjust the trim. It sucks. I haven't tested much above 2A to see if the offset "increases" or if it's just a 300mA DC offset (pretty sure it'll increase by 30% so with a real 5A load 1.5A fail). Update and I tested at 3A (actual) and the reading was almost 4A with a 30% deviation. That's some nonsense.
