Gee, I've NEVER had one fail in any of the gear I have.  I 
did have an "X" capacitor fail in a big switching power 
supply, but this was just a capacitor on a board.  I've 
never had a Corcom or other brand of power entry/line filter 
go bad.

So, I think that one particular type might have had some 
kind of manufacturing defect.
