Product review (1 stars): Doesn't seal well out of the box.
Bought two of these for one of the LG refrigerators this is advertised for.  In both cases the filter did not seal and water leaked into the refrigerator.  Some plumber's grease took care of it, but it took some fooling around to get it to seal.  The official LG filters I have bought in the past work the first time every time.  Filering seems OK but that is hard to assess
