Product review (5 stars): Does the job
I never understand why people insist on getting the brand name item.  This works.  a little tip I could have used when I did the installation: turn off the water under your kitchen sink before you replace the filter.  It was like being in an I Love Lucy episode, the water was spraying everywhere.  When the fridge was new it presumably came with a new filter, already this knock off filter which was a fraction of the cost has lasted much longer.
