Product review (5 stars): Worked as advertised!
So far so good.  Took the advice from others on this page and removed the washer prior to installing the filter.  No leaks and pressure was just as good as the GE OEM filter.  Just make sure to follow the directions and run for 5 minutes in order to get all of the air out of the system.  Taste the same as the other filter for about 25% of the cost.  I already ordered up some additional filters to keep for later.
