Rated 4.7 out of 5 by 20 reviewers.
Rated 5.0 out of 5.0 by Simple, effective .... This timer was bought for the sole purpose of controlling exterior Christmas lights automatically (interior use of timer with garage outlet and commercial extension cord). It is a simple "plug, program and forget" design which is compact and quite easy to use. Simply place one "pin" into a time slot for "on" and another for "off," adjust the center dial for actual time and let it run. Three sets of pins allow three separate start/end programs daily. Must be something you need daily - not able to pick and choose days of the week with this one. Also features a manual on/off switch for overide without removing pin settings. All in all for the price and ease of use, I would recommend highly. December 11, 2014

Rated 5.0 out of 5.0 by Best Timer!!! Bought a few of these timers years ago in the HD store by my home but they only carry them online now...My grandkids took the little green & red on/off picks out and lost them on 2 of my timers and I really wanted a few more anyway. These come with 2 sets of red & green on/off picks so I was able to use them on my timers that were missing the picks which worked out well.... These timers are so easy to set, very quiet and work like a charm...Thanks HD for keeping these in your vast array of home items. Just wished you still carried them in the stores... June 24, 2014

Rated 5.0 out of 5.0 by A Life saver We purchased this timer because the automatic toaster oven was left on over night at work and the food inside was black (French fries).It could have burned down our business. Now we have it on the oven and the coffee pots. A life saver. We didn't take a picture of the fries. December 30, 2014
