As you can clearly see the plastics on the door bell have become brittle, cracking on the body itself and the button has degraded and has split open.  I this is due to poor quality plastics used, most likely damaged by UV.  This is shocking or a door bell that is just a few years old. Im in the UK where we don’t get months of sunshine, so how bad can these plastics be?  I can only hope Ring read this and do the right thing by replacing it.
