Product review (1 stars): Water Sentinel Filter
Does not work on my GE refrigerator. If you use the O-Ring it will not dispense any water. If you  do not use the O-Ring and you activate the door water dispensor then it leaks considerably at the filter assembly.  I contacted Amazon for return info and they said to contact Water sentinel by email.  I did three days ago.  Have not heard back from them as of today 2-19-10.
