Query: Great timer - easy to install - easy to set up

This was the least expensive timer switch I found on Amazon with the programmable latitude/longitude coordinates. It arrived quickly and I had it installed in 5 minutes. The only thing I didn't like was the cheap screws that it includes. The heads are soft so make sure you have a screwdriver that fits well or you'll round off the heads.The instructions were clear and simple. They include lat/long coordinates for major cities, but I got them from Google for my town and that worked too. As soon as I entered the data, the light came on - just like it was supposed to.The switch body is fairly large so make sure you have a full depth switch box that isn't full of wires or it may not fit.
