Product review (1 stars): This Filter Leaks
The truth is, GE holds a patent on the design of the filter connection.  It's a smart approach since GE charges a huge markup on a very inexpensive item to manufacture.  Some non-GE replacements can still provide an adequate connection by re-designing a connection that works around the GE patent and provides a lower cost option.  I can tell you from experience that "Water Sentinel" has not designed an effective connection to bypass the patent.  So what you'll get is a leaky gasket, and water inside your fridge.  I would highly recommend you avoid this product and seek out a non-GE replacement that isn't known to leak.
