Bests & Worsts Reviews from Amazon

This switch looks good and works well (see added information below). Other reviews have commented on its operation. I would recommend it, too, but not until Honeywell includes a backlight or other illumination for the display. I installed the switch in a dark hallway and had to use a flashlight to see the display when I programmed it. I found the timer easy to program, though, and easy to install. Someone else noted you need three (3) wires--power (black), neutral (white), and connection to your lamps or lights (probably black). That's correct. To find out if you have the required wires, turn off power, take your old timer or switch out of its electrical box, and ensure you have these wires. DO NOT connect the neutral wire from the timer to the bare ground wire in the electrical box. Addendum 17 October 2012: This timer worked well for about 10 months and then died. I went through hell to get the Honeywell warranty-service people (call center in south Asia) to respond to my requests for a new timer under warranty. All they wanted to tell me is what they could not do. After three calls, I talked with an Amazon person who called Honeywell and got things squared away. I still had to make a final call to the warranty phone number and email an image of my Amazon receipt. Honeywell's customer-service treats customers poorly and I will not buy another Honeywell product unless absolutely necessary. I was surprised the warranty-service person did not ask me to return the dead timer. I thought the company's quality-control people might want to determine why it failed. Maybe they don't care.
