Product review (1 stars): One star for the good customer service
One star for the good customer service.  0 stars for the product.  Bought this back in September and even after being sent a replacement, it still does not work as advertised.  For the last week, the indoor monitor has been telling me its 20 degrees warmer outside than it actually is.  I have a sensor placed 100 feet away in a seedling shed, and it hardly ever reads it.

I would call them again, probably for the 4th time, but I am done wasting time on a product that I know just does not work as well as they say it does.  I don't like leaving negative review but I feel that it was warrented this time because I would have never bought it if I knew it wasn't capable of reading less than 100 ft away.
