Product review (5 stars): Good Filter, a Bit Pricey
Works like a champ, though it was a bit unclear how to reset the fridge's "replace filter" light.  I eventually figured it out; will probably be lost again when/if I replace it down the road.  That says  more about a lack of the fridge's instructions rather than the filter itself of course.

UPDATE:  Didn't really last all that long...it's already giving me a "get ready to replace" message after only a few months.  I don't blame the filter here; I'm not all that happy with the apparently planned obsolescence.  Might or might not bother to replace it when the time comes.
