Review on 🔌 DROK USB 3.0 Hub Multi Tester with OLED Screen: Pocket Digital Multimeter, DC Voltmeter Ammeter, Capacitance Meter, Thermometer, Energy & Time Battery Monitor, OTG Connector Output with Auto Off by Mike Calderon

Only used 1 day but seems to work as described. I can't verify the readings, but they're in line with my expectations from the usual tests I've tried. The instructions were difficult to read due to the very small font with black text on a glossy blue background. All control is done with a single button (on the back of the display), but after reading the instructions a few times and playing with the button as instructed, I finally figured it out. (If I could, I would change the short press and long press value in settings mode.) Anyway, it works and also allows you to transfer data over USB3 (aka 3.0 or 3.1gen1).
