This programmable thermostat has served us well. It is in our master bedroom and we change the settings for the school year and for summer break.
There are only 4 buttons so there is a lot of scrolling to get to the whatever you want to change, especially if you make a mistake but my larger complaint is no light. I come to bed after my wife and I don't want to turn on the bedside lamp to temporarily adjust the temp so I just have to trust my sense of touch.
If you put it in an area that has a constant light source or where turning on a light won't bother anyone it is a perfectly simple, no frill thermostat
