It simply can not be easier to use especially if your looking for dusk to dawn operation. I have another one of these installed for the front of our house for 4 years now and it has worked flawlessly.

Purchased as a replacement for prior identical unit which worked perfectly for six years until it died. I think six years is acceptable given it is mounted outside and continuously exposed to the weather (New England).

Very simple to use and I have had no problems in 4 years now. Features for the $$ are outstanding.

Maybe I pushed the setting button too many times today but it does not work now! DON"T WASTE YOUR MONEY!
