Product review (3 stars): Not quite as good as the factory filter but...
This one seems to leave just a little aftertaste.  Another thing I noticed is it drips after each use. I really don't mind it that much since I am more driven by the value than performance of the filters.  Then again I will have to live with the decision for the next year to 18 months having bought the 3-pack so maybe my opinion will evolve.  As a final thought, I can certainly see myself splurging next time to cough up the extra money for the OEM filter.  It's hard to put a a price on good clean water and the OEM filter was excellent!
