Rated 5.0 out of 5.0 by Perfect For Outdoor Lights We installed this switch for the outside lights on our front porch and for the back yard. Works very well for compact fluorescent bulbs. Very dependable. Be sure to get the heavy-duty switch to prevent flickering. July 16, 2013

Rated 4.0 out of 5.0 by Should be stocked in stores Purchased Defiant timer because it didn't require a neutral wire. big mistake! It was impossible to program because of the lack of backlight on screen. The intermatic should be carried in stock. You already stock Intermatic products . Also online price is quite high compared to other sites December 10, 2013

Rated 4.0 out of 5.0 by This product works well so far. I've had this timer for about 3 weeks, and so far it is working well. It took a little effort to get the dusk/dawn program to work, following the enclosed instructions. Other than that, no problems. October 8, 2013
