Product review (5 stars): A Must Have in Your Home
This is the first time we have ever used a hygrometer in our home.  Very pleased with the ThermoPro TP50.  It was delivered promptly.  It is small enough to fit on an end table and the numbers are large enough to see clearly.  If you use humidifiers, I would highly recommend this item.  Very easy to insert battery and only takes a few minutes to reach humidity levels in your home.  I also like the high and low levels that are shown, as well as indoor temperature.  Saves running your humidifiers when they aren't needed.
