    It feels strange rating contact sensors. Because they either work or they don't. These work just like any other contact sensors except they feel very sturdy. I have other contacts sensors from other manufacturers, and these are definitely more premium. I sure do hope so because they are so expensive. they all communicate properly with the base unit no matter where they are in my large house.
