Product review (4 stars): Good, but rinse through a few times
products were shipped quickly and fit our Kenmore Elite Refrigerator nicely.  Be forewarned, however: be sure to run a few pints of water thru the unit once it's installed to "charge" it and rinse out what I assume to be granulated charcoal residue.  I switched units, then ran water: at first, it ran fine, then went dry, then went to new water, then went to black water, then to brown, then to colorless.  After about 2 pints, all is fine.  I think the filters are fine, but that first few cups of water need to be discarded.
