Product review (5 stars): PREVENTS FROZEN PIPES AT OUR SECOND HOME
We have a vacation home in another state and go there to check on things every two or three weeks.  Unfortunately, last February we arrived to find our baseboard radiator pipes had burst and the water had destroyed two levels of our home.  Nine days earlier verything was fine, but sometime within those nine days, our furnace stopped working.

We asked ourselves, how could we prevent this from happening again?  The obvious solution was to find a way to constantly monitor the indoor temperature and know when it starts to drop so we can get to the house before the pipes have a chance to freeze.

We love that this comes with three sensors.  It's just more peace of mind knowing that if one sensor fails, we can still rely on the others.  I highly recommend this product for anyone with a second home or even to use at your main home when you travel during the Winter months.
