I have had the ThermPro for a week or two and needed it mostly to check humidity during dry winters.  I got so much more than I expected.  Firstly, it is a very neat design and the numbers are clear and easily readable.  It gives me more information than I expected.  It shows current humidity and temperature in the room, as well as the high and the low of each of those readings at any particular time.  It gives you ranges when the room is too dry or too humid and tells you when it is in the optimal range with the word "Comfort" and a smiley face.  So I know exactly when the humidity is in the desirable range.
I am very pleased with it so far.
