They're good (S&J) but I've never had a factory/orange one fail either. They look pretty flimsy when I take them out for cleaning, but then they just work fine all the time like they should. Add/don't add~I doubt you'd ever see a difference in performance..but no doubt, the S&J one is nicer/more robust/affordable upgrade, etc.
Agreed~S&J are superb to deal with.
