Product review (4 stars): YO - where is the "O"?
This filter does not include an o-ring seal at the inlet.  I thought that was odd as the other GE filter had the o-ring.  It concerns me about the long term leak-proof-ness of the filter.  And peace of mind as well - not having to check it for leaks each time I look into the refrigerator.  So far so good.  It's been installed about 10 days.

Water quality (after flushing the 1/2 to 1 gallon of water) - a 10
Clarity - 10
Taste - 10
It's just that dang no o-ring thing.
