    We have both the 1st and 2nd Gen sensors in our house (bought at different times) and both were pretty straightforward and easy to install on our windows and doors. Syncing these to the Ring app was also easy to do.

    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.
