Product review (5 stars): The Ambient Weather WS-11 is Great
So far, this unit has worked perfectly.  It was easy to set up (read the manual) and the temperature readings are spot on.  Checked against a known source.  The outdoor sensor about 45 feet away was picked up immediately.  The sensor scan icon is hard to catch because it only flashes briefly.  It's located  by the channel icon.  The external power supply developed a bad hum and was immediately replaced by Ambient Weather.  They answered my email the same day.  Your going to like this unit.
