Product review (5 stars): Working Flawlessly for Over a Year
I purchased this product in November 2014 to monitor a second home that I had just purchased in Maine.  Because it is a second home that I would be away from for the winter, I wanted to be able to monitor the temperature to make sure the heating system was doing it's job and that there were no events such as a broken window, etc.  While I was still there, after setting up the unit to make sure it would do what I wanted, I ordered a second sensor so that I could monitor both the main living area and the basement.

Over the past year plus, the set up has worked flawlessly, to the extent that I am today ordering a duplicate setup for my main home here in Maryland so that I can monitor this property for the 2 1/2 months that I will be a way in Florida.

Would I recommend this product to a friend?  Well, I did exactly that to a neighbor who wanted to keep tabs on their summer place on a lake in Maine.  He set it up and is thankful that I told him about my experience with the product.
