Product review (5 stars): Water tastes much better
I wondered about these because they were cheaper than the LG brand, but I have been very happy with them.  I am pleased with the filtering capability - the taste of my water (and ice) is quite different than tap water.  Funny how you don't notice your tap taste until you've had something else.  My refrigerator warns me when it is time for another filter...I go by the usage of water and ice, rather than a number of months.  Obviously, a family of 5 will use more water than a single person, so the family filter would have to be replaced sooner.  Fits well, delivered as expected, and product was as described.
