Product review (4 stars): Awesome little thermometer!
So far so good! We bought 4 & like other reviewers here we tested them next to each other in the same room. They all registered within a tenth of a degree from each other. Humidity also dead on. We have since put them in several rooms in our house. Would highly recommend them!

My ONLY complaint (which seems moot at this price point) is that they don't light up at night. I would love a little button that I could hit, light up the face & check it at night. We use it in my child's room so that would be especially helpful.
