Product review (2 stars): Leaky mess under sink after install.
The 1st cartridge developed a slow leak and ruined a carton of DW soap. The 2nd one seems better, but both produce much greater volume and velocity of water flow than the GE GXRLQR these replace.  To me that indicates that there is less filter material the water passes through and possibly less overall filtering.  These are going back as one failed entirely and they don't seem as well-built at the GE units.  Lessons learned.
