Product review (1 stars): Unreliable
Owned this thing for a week or so then, Once the temp outdoors dropped below freezing, this thing went wacky.  It began reporting insanely incorrect temps (158 deg F!) so I pulled the new batteries and did essentially a reset.  This fixed the problem for a day, then the same troubles.  This thing is useless as it only wants to function normally some of the time.  Poor QC by manufacturer on this one!  Now, off to find one that actually works as advertised.
