    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.

    Put one on each window in my house. Just realized that if someone throws a rock through the window these will not send an alarm since their "contact" has not been broken. But, if you have an Alexa echo nearby you can use Alexa guard which sets the echos to listen for broken glass and fire alarm sounds. I'm sure best buy would install these for 99/each lol.
