Our bedroom has a light bar that was installed before we got the house. The only way to turn them on or off is to plug them in or unplug them from the wall. We use it every day, and it's inconvenient to look for a plug on the floor in the dark. This switch is perfect, now we can use it instead of making rough movements by turning it off every time. I also love that it doesn't have a glowing indicator when it's on or off at the switch itself because I think that would be an annoying feature in a dark room right next to our bed.
