Product review (5 stars): Setup was easy. Just insert batteries and place the sensor outside
No complaints whatsoever.  Setup was easy.  Just insert batteries and place the sensor outside.  I hung it by a piece of nylon twine in a magnolia tree in the front yard.  It is protected from the direct onslaught of the major rain storms we get in Florida but accurately reports the temperature.  The display is easy to read and it seems to work anywhere in the house.  And the best part is no wires.  My cat shewed the wires in half on my old unit.
