Rated 1.0 out of 5.0 by Didn't work right out of the box Purchased because it seems reliable. Had it professionally installed, the manual operation works but timer doesn't. Now I will need to pay a 2nd service call to an electrician. Not a happy customer. May 23, 2015

Rated 5.0 out of 5.0 by Simple and durable My backyard has a 30-40 year old timer already(same model, same design) and its still working strong. It ticks a little louder than the new one I just installed, but only if you head is next to it. The new one is very quiet. The design is simple, and everything is sturdy. The main component comes off very easily with a snap at the top. Remove, install box on the wall, then snap it back in. Basically I connected the line from the breaker to the Neutral and Line screws, then connected the Load(my two front lights) to the Load and Neutral screws. Ground to ground. took 15 mins. Setting the timer and the on and off switches took seconds. Highly recommend for this application! And I know very little about electricity. Of course turn off the power before working with it ;) Thanks, HD! April 8, 2014
