That sounds promising.
It seems to work on the door opening and not on mail being placed in the
mailbox.

I wonder how that chime works in an all-metal mailbox.
(How does it figure out that the door has been opened?)

The ad doesn't say HOW it figures out that the mailbox has been opened.

I'm pretty sure it senses motion from opening the door. It makes sense
because it says it will not work on vertical hinges but it works with
the three pictures. On a vertical hinge it would only swing out, not
tip over.
