Essential Info

The uTimer Light Switch allows you to keep the light on in the room only when you are in it. Plug the desired lighting device into the uTimer and then plug into any standard AC outlet. Motion-sensing technology embedded within the uTimer will detect movement and automatically turn the lamp on. The light will then turn off after a pre-selected time of inactivity (1, 5, or 10 minutes). Perfect for hallways, foyers, bathrooms, basements, garages, or anywhere else you might need light for short periods of time. The uTimer eliminates the hassle of searching for a light switch, making for hands-free lighting in almost any application. A special photocell makes sure the uTimer only operates after the sun goes down so you can be sure your lamp is not activating during the day when unnecessary.

    Agree with Gail, this product does not work as advertised. It wont shut off and the plug in is reversed, so you can only point it down at the ground.

    Simply works. Refreshing.

    This product does not work as it is advertised. It does not turn itself off. If you want to use it as a nightlight, it's fine.

    This product did not work as advertised. It turned itself on, but never went off unless you turned it off. I was very dissatisfied with this product.
