I'll try and keep it short and sweet. I love this thermostat. The dimming function is exactly what you need if you are using a deep heat projector. The temperature is fairly accurate (within 1/2 degree or less from other thermometers). The ONLY thing that is a pain in the a$$ is the dial you use to change the time/temp...you either need a longer nail or perhaps a flathead screwdriver to turn it. It's a pretty bad design flaw but not bad enough to drop it down a star...because once you set it, you don't need to mess with that dial again (unless you want to adjust the temp/time again for some reason).
Just an FYI...there is no alarm on this thermostat.
