Product review (3 stars): Not accurate
The packaging and delivery was very good.  Seller did a great job there.  The thing I am not too happy with is that I bought a total of 4 of these and when I line them up together, side by side, they all have different readings.  No biggie as I don't need absolute pin point accuracy, but it is weird to not know if the room I am in is 67, 68, 69 or 72 degrees!  I am only using one outdoor sending unit, so they do display the same outdoor information but indoor, side by side, there should not be any deviation.
