I gave this thermometer 4 stars instead of 5 because it is very sensitive. Or maybe it is afraid of the dark. You see, I keep it in a drawer. It really, *really* seems to like being used because every time I open that drawer something bumps against it and I hear the little chirp of my thermometer turning on.
Also, one time I heard a very quiet high-pitched sound and it was the thermometer which was on. I had trouble figuring it out at first, but the sound was so persistent that I finally figured it out. So now I am paranoid when I open the drawer and hear the chirp, that it will stay on and make that noise again.
