Works great. I had a problem when testing. When I applied power to the module, the blue LED did not light up. I emailed dsd tech and they responded within hours with a "make sure you do" list. Details that solve common user error problems. Of course, the 12V power supply I used wasn't "stable" enough to power the module. It was an old car charger. Connected to a 12V power supply and it works great. I use it to control an off-road light relay on my Jeep so I don't have to run wires through a firewall and set a switch.
