Product review (5 stars): Works great so far
Works great so far... as advertised.  I haven't had any problems... but I read about a few others that did before I bought it. Mostly about it having issues if you put in direct sunlight.  So I placed mine in a spot outdoors where it wouldn't get rained on or be in the sun (which you don't want anyway for reading out door temps or humidity).  Great product if you use as directed.
