This is an easy way to connect two devices to the same modem line, but only one can be used at a time. For example if you are a gamer. If you have two devices and only one Ethernet cable in the room, you can switch the line between devices with the push of a button instead of having to unplug and plug the cable between devices every day. cheap, but that's because it's cheap. Kids use them so the pair have been stress tested and so far so good. Will come back to this if something goes wrong. Recommend and buy again
