Product review (4 stars): Maybe as good as the original....
I haven't used this filter long enough to give it a "5", but so far it appears to be as good as the OEM filter.  It isn't packaged quite as well as the original, but it isn't nearly as expensive, either.  If it continues to perform as well as its OEM counterpart, I'll upgrade it to a "5", and it will be my filter of choice in the future.
