Upon obtaining this, I tested it on my own camera after installing the batteries. I also tested the "test" button. It worked fine at that moment.
When I pulled out the batteries, a metal part of the battery interface broke loose. You can see it in the pictures.
This is an easy fix for someone who knows how to open this up and replace the battery receptacle.
