Review on ECOELER 3-Way Motion Sensor Light Switch, Neutral Wire Required | UL Listed & FCC Approved Indoor Activated Switch | 1 Pack by Don Leblanc

I bought this to replace one of a pair of standard 3-way switches controlling a laundry room light. Just be aware that the wiring on the remaining switch needs to be changed to support this switch. Pay close attention to the wiring diagram packed with this switch. It said to move the black "line" wire to the same terminal as the black traveler and then connect the common terminal to ground. I did move the "line" wire, but did not connect the common terminal to ground, and it works fine. Connecting the common to ground seems wrong to me. I like the fact that you can set the light sensitivity of this switch so it does not turn the light on when daylight is coming through the window. You can also set the amount of time before it automatically turns the light off. Plus, you can still turn the light on or off manually using either switch. This is a great buy since typical motion sensor 3-way switches run $20+.
