Product review (5 stars): Found out that the GE replacement is the only way to go...the hard way.
We went with a cheaper, non-GE version of the filter this week to save half the cost of this filter.  That wasn't worth it at all.  That generic filter is back in a box ready to go back to Amazon.  This one is installed and working great.
The generic replacement was noisier and left our water lines dancing around loudly.  We ended up licking the water dispenser until we got the GE replacement part today.  Whew, it's back to normal now that we have the real thing.
