The original wall sensor switches in my house didn't use power neutral line. They were okay for fluorescent or incandescent lights. After replacing those lights with LED ones, I saw a problem. LED lights were unable to be turn off completely. These sensor switches can solve the problem.
The Lutron Motion Sensor Switch is far superior to the Lev**n product. It does not randomly energize the load as the other manufacturer's product does.
Replaced my New motion sensing switch with this "Lutron" Motion Sensor Switch, it works great. only took a couple of minutes to install and it is working like a charm. I'm sold on "Lutron" Motion Sensor switchs.....
