    Love these. I originally bought the security kit that came with 4 pairs of these, but needed more for my doors and windows. It’s so much cheaper to buy the 6 pack, compared to the single and two pair sets. I love being able to hear when doors and windows are being opened in my house.

    One of my Ring contact sensors got damaged and wanted to find another locally versus ordering online. Best Buy had exactly what I needed at same price as ordering online. Bought a 2-pack so now I have an extra one. Was very pleased.
