Product review (1 stars): WARNING! GE will not honor warranty
Water passing through this filter was painfully slow. We waited patiently hoping the water pressure would increase over time. After several months, I called the GE answer center. They had me remove the filter and use the by-pass plug. The water pressure was normal without the filter installed, so the problem was the filter.

Then I got the bad news. GE says Amazon is not an authorized retailer and they would not replace the filter. They said "Don't ever buy them on-line because we can't guarantee the quality." I hope Amazon will work with GE to resolve this issue.
