When we moved into our house mumblesomething years ago, the doorbell was broken.  We replaced it. 

Then that broke. So we got another one.

 Then that stopped working. I bought a new receiver for the button.

 Then the button broke.  I bought a new button.

 Lather. Rinse. Repeat... in one form or another.

 I'll bet I've purchased half a dozen or more new attempts at making a doorbell for the front door and not one of them worked for more than a year. 

It's taken more than a decade but I think I've finally fixed the doorbell.


Hopefully that one will last awhile.
