Product review (4 stars): Excellent
Great filter.  Works as advertised.  The only thing that I don't like is that for the first gallon or so, the water sputters out of the dispenser while the filter is "primed".  I don't know if that is a function of the filter, or the refrigerator, however.  I'd give it 5 stars, but at the end of the day, it's a filter.  If it was cheaper, I'd give it 5 stars.
