Does the job, but not well made.

This does the job, it measures current/voltage, and is a useful diagnostic tool. It tells you how fast your device is charging, allows you to test different leads and USB ports/chargers.
However it feels poorly built. I get the impression that is will fall apart at any moment. The USB output port is also at a slight angle, as if it is loose inside.
