Product review (5 stars): Seem to work well and easy to read.
These seem to work really well. The display is clear and easily readable. They give a indication of Temperature and Humidity. I have not checked them for accuracy but they seem to correspond to our other readouts. These are a good way to see if your humidifier (or dehumidifier) is working. Especially in the Winter when the humidity in the house is drawn out by the furnace.
