This is a manufactured device, made is batches of 100's.
This is the only one that has been returned in this condition.

Batteries have been installed wrong, but the unit just stops working
when the batteries fail. Others have had screwdrivers, pens and other
things put throught them, but the PIC has yet to explode.

I'll be able to get a picture of the device next week. Both a working
unit and the one that has been destroyed.
