Antique Brass is disintegrading from doorbel, only after 3 years!!!
Hi there @KSlind66. If your Doorbell is showing any signs of physical wear or damage, it would be best to reach out to our support team so they can review the damage and check the warranty on the device. You can give our support team a call at one of the numbers available here. We’re taking additional steps to protect our team and help reduce the spread of COVID-19, so this has resulted in longer than normal wait times. If you are outside of the US, please read our response to COVID-19 here to see how to contact support. 
For a quality product what ring is, it is not expected that this can happen
