Both of the cartridges have performed well below expectations.  They cause serious vibrations in the water line after a few weeks of use.  After the first one failed, I installed the second.  Noise went away, but a few weeks later, and it is back.  I will not be purchasing these again, never had this issue with the more expensive Samsung filters.
