Wiring was super intuitive and everything just worked. I was able to power, ground and provide signal all from Arduino and then pull 12V DC from a 4A dedicated power source and connect it directly to the 12V DC magnet when the relay receives a signal. Perfect solution for my secret bookcase door project!
Only note was that the relay screws needed the perfect sized screw driver because it felt like it was going to strip with the one little screwdriver I use for everything so I had to get a new small screwdriver kit and then i was able to repeatedly install and change configurations on this board without any problem.

Works well, but it is NOT a bistable/self-latching relay. Requires power for the NO contact to remain closed after engaging the relay (and the opposite for the NC contact). The control line (marked "IN") must be held to the same level as the jumper to keep the relay engaged, i.e. if the jumper is L, IN must be 0V/Ground/Low, if the jumper is H, IN must be 5V/High.
Info: 5V relay uses 1ma with relay off and 64ma with relay on.
I'll probably find a use for these relays, but I am disappointed that they are not true self-latching relays.
I don't know the duty cycle of the relay, but it gets slightly warm after a minute, and I've left it on for at least 10 minutes straight so far with no problem.

Works very well / shipping not so great

Some how the units work as they should but, as you can see in the picture the package was not protected with bubble wrap or a small box. So expect the one that you order to be damaged. But for the price can't beat it.
