Exactly as advertised. Plug it into any USB-A connection (between the computer and the Arduino in my case). He sits there, doesn't disturb, shows the voltage in red and the current in blue. The LEDs are easy to read even with bright workbench lighting. Yes, a multimeter poking into the right pins will do, but it's much easier to just have a constant current reading to look at. The device is as small as it gets but fits on USB-A ports and is beautifully finished.
