Customer Reviews

Rated 4.8 out of 5 by 13 reviewers.
Rated 5 out of 5 by excellent product This is the ideal solution for any light you want to control for nearly any time period. It will do dawn-dusk or any combination of on-off programming you can think of. Perfect for outside lights that don't have photo cells. May 13, 2015
Rated 4 out of 5 by Good choice for whole house window candle circuit This unit has a dusk and dawn calculator by latitude zones. Coupled with the random function, it is great for our window candles as they come on "around" dusk for the time we use them as the days are mostly getting longer each day. The shut down time is also randomized, so it gives the appearance of a lived in structure whether you are there or not. Programming is tedious, but not difficult. Hope the battery lasts a good, long, time. January 26, 2015
Rated 5 out of 5 by Most reliable timer on the market for small loads This timer is the most reliable timer I have ever found for small electrical loads. Light outside lights. Only maintainance is a battery change every few hours. love this timer November 7, 2014
Rated 5 out of 5 by Good Product little pricey but works well and works with cfl's March 29, 2012
Rated 5 out of 5 by By far the best timer for our customers We use these timers in landscape lighting installs and the result has been fantastic. There are about 10 of them that have been in for over a year and have been working without an incident in failure. We can not say enough about the quality of these timers. Had a customer request that we use the GE timer that the home improvement stores sell, so I checked it out. The people on the floor at the store said that every one of the GE devices that they have sold has come back. Not a good track record. March 2, 2012
Rated 5 out of 5 by Great Product I love this product. Its easy to install and with the daylight saving feature, once you get it programmed, you dont have to worry about when your lights are turning on and off. March 1, 2012
Rated 5 out of 5 by Great alternative to light sensors Looks good, works great, automatic dawn/dusk setting works great. Have installed in two different houses I have lived in. October 5, 2011
Rated 4 out of 5 by Works Great, But Observe Max Wattage The product performs as advertised, which is very good, but if you are even within 80% of the max wattage rating, you will find that you have to replace it pretty often. June 30, 2011
