Bests & Worsts Reviews from Amazon

So, basically these Chimes ONLY work with the Ring Doorbell System, but NOT the Ring Security system. This makes this product essentially worthless in my opinion. I have both systems, and maybe I am crazy, but the Ring Doorbell system devices and the Ring Security system devices are apparently NOT always compatible with each other!?!? How is that even possible in 2020?? For example, if you want to hear a "chime" alert, if a door contact sensor is opened, it will ONLY play on either the Base Station (in my basement) or the Keypad (up by the Front door), but NOT on any Chime units?? Really?? What moron designed this product??? you can ONLY hear the doorbell on these Chime Units. Nothing else apparently, even though the system has other sounds related to the security system. So, If you house has a second floor, and you need to know if a door is opened downstairs, then you can't hear the door contact sensor chimes, if you are too far away from either your Keypad, of from your Base Unit, unless they are very close to your location, unless the criminal rings the doorbell first apparently. I thought that would be the whole purpose for having a system where ALL devices are compatible and ALL work together, but apparently not. I've never seen a product line with: one name; one app; and one website, BUT not all its products work with each other??? Unbelievable. Save your money, and buy another system.
