    I bought these in addition to the entire Ring alarm system and doorbell. All my doors and windows have one of these installed. Better yet, the installation was free with the total tech program. I really can't say enough about all the free installation I've received.

    Love these but still need more. I am concerned about the battery part coming out if not installed a particular way and worried when I move would i have to repurchase new ones or does the sticky tape let me replace it? Basically what happens when I want to move?
