Product review (3 stars): So so
Well I got this because of the great reviews. So far the outside temperature has not been accurate. Disappointed.

10/26: I have to say the company is great. They sent me a second unit on their dime. Great customer service.  With my 2nd unit the outdoor temperature still seems way off.  I put the batteries in the sensor first. The sensor is about 20 ft away.. If that.  It says 31 outside however on this device it says it's 40 outside.
