Works as expected. I'm using it to take 12v signals from a car (turn signals, brake light, headlights on/off, lock and unlock) and use them as buttons or switches on my esp32. I took off the crappy screw terminals and soldered wires directly to the board and covered the thing in hot glue. Hopefully that adds to the longevity of the thing.
