Product review (5 stars): Accurate and reliable
I love this thermometer.  We've had similar products before, but they usually stop working or transmit very poorly.  I keep the outside transmitter on our back porch, as it says to keep it out of direct sun and sheltered.  The receiver is in an upstairs room in our house, and seems to register everything accurately.  I love that it displays humidity as well as just temperature.  Here in Atlanta, that is just as important as temperature!  Arrived on time, easy to set up.  I put both parts out side by side in different environments (inside and out) to test that they were recording/transmitting the same readings, and they passed my test.
