Product review (1 stars): They don't work!
We had our appliance man try to install both of these filters in our G.E. refrigerator.  Neither one worked.  I have purchased this exact product in the past and they worked fine.  For some reason there's been some slight changes in the openings of the filters that prevent them from installing correctly.  (We could see the difference from the one he removed.)  It's very disappointing since a new G.E. filter is $50.  If you're going to sell a generic filter, it should at least be able to fit in the refrigerator and work!
