Product review (5 stars): Has worked fine for several years
We tried several other units -- more expensive and none of which worked well -- before trying this one, which is a winner. I didn't want a forecast or lots of complicated readings that I had to figure out. Just a unit that gave temperature and humidity outdoors and inside and could be read at a glance. It's worked just fine -- no problems whatsoever -- for several years. We have a regular thermometer out back near the transmitter and they report the same temperature.  The humidity levels are about the same as given by the local National Weather Service office. Reliability and accuracy have been excellent. Can't ask for more.
