Product review (5 stars): Works great!
For about 5 months now we have been using this thermometer.  I love that the indoor reader can be moved anywhere in the house. Often times I have it sitting in the kitchen and can view the temps quickly. Now that it is summer and we are running the air conditioner it is handy to look at the indoor temp vs. the outdoor temp and the humidity to help know when we should turn the air on in the morning and when to turn it off at night and open  up the windows. It is also nice to see the humidity in the house in the winter to know when we need to increase the humidity to 40% in the house for the winter for better air quality. So happy with this purchase!
