As soon as received it I've powered it and put the three wires in water. It works as described. Common wire at the bottom of the tank, when the upper wire touches the water the relay toggles and then toggles back only when the lower wire is out of water. Adjusting the position of the wires you can easily choose the positions when starting to pump and stop. Of course if you want to feed a big pump with amps the relay is too weak and it'll be considered as a driver for a bigger one, but that's not a problem. It's a 5 stars device for sure!
