Honeywell RTH230B 5-2 Day Programmable Thermostat

Everything works exactly as advertised but I understand there are other programmables that do not require freguent changing of batteries--a bit of a pain.

The 4 programs per day is terrific. Definitely helps to adjust for our work schedules. Installation was a breeze, but I would recommend having a "smallish" slot screwdriver on hand, in addition to a regular sized philips.

This product is a great deal for the price.

It is easy to install. It took about 30 to 45 minutes to complete the entire process and can definitely be done by anyone who can read and follow directions and also has some common sense.

My only suggestion would be to make sure that you have the smallest Phillips screwdrivers possible because some of the screws are quite small.

You will definitely save money on heating/cooling if you are replacing an existing non-digital thermostat. I am already turning the thermostat down to exactly 58 degrees at night and only up to 68 during the day.

This is an excellent programmable thermostat. Very easy to program and works excellent. Very accurate.

I found the instructions confusing at the most key part, ie, where to insert the wires, and where the J-switch goes. The screen doesn't light up which is a pain when trying to check temperature or change settings at night. You have to take the cover off to change settings, the cover doesn't flip. The screws were difficult to access with a standard Phillips head, down in narrow channels. You have to toggle between one display to see actual temperature vs set temperature, instead of being able to see both at once. I'm frustrated enough that I'm going to switch to a Lux model which I'd installed before and loved.
