“I purchased a new garage refrigerator for large items like brisket and turkey. The Beacon transmits thru the fridge wall and a brick wall. My other sensors wouldn't do that. It monitors the temperature and gives me peace of mind. Unexpectantly, I also know how the fridge cycles, what cold colder and coldest means, and have a log of when my beers were pilfered (I'm not proud of that). A great product.”
