Product review (5 stars): Helpful for pet owners!
We got this to keep an eye on the temperature in our house when we travel. We live in the desert and during the summer months it reaches over 115 degrees outside, being 120+ inside. If your air conditioning quits, your pets will die within hours. This alerts you when the temperature reaches a set "high point and low point". This is worth the piece of mind knowing the temperature of your house.
