DROK DC 5V~18V 12V Home Light Control

Got the product, installed it and it doesn't work. Tried troubleshooting it but there's not much one can do except play with the sensitivity adjustment. Maybe I just got unlucky and got the one that was due for MTBF reasons :)

Nothing exciting here. It's a switch. Hook it up and forget it.

There's no instruction, and it doesn't work.

Just what I needed. Works they way it should. Prompt shipping.
