Works great! I bought these to close the switches in my laundry room as I have a motion sensor there. The screws were long enough to reach the box. You can still turn the light on and off by sticking your finger through the small holes (a pencil is cooler, but it's nice to know you can toggle without tools too). This works great for me because I never have to manually change the switch. The transparent color makes them not very noticeable. Will buy again if I ever need a different switch cover!
