I have several of these for a long time. They were previously sold as White Rogers, now sold as Emerson. The electronics have changed over the years, but the outside shape and the model number did not. The thermostat is easy to operate and program, and I like that the LCD shows two temperatures at once: the current room temperature and the temperature the thermostat is set to maintain. One glance, and you know everything you need to know.
The LCD is not backlit: if you plan to check the settings in darkness, you need a flashlight. This thermostat has only two programs: one for all weekdays, and one for the entire weekend. This is called 5+2. If you need more granularity, such as 5+1+1 (separate programs for Sat/Sun), or seven days (separate program for each day of the week), you need something else. Programming such a thermostat would take longer though, so only go for it if you really need to.
