Product review (4 stars): Seems to do the job
I'm not sure how to define good versus great on a water filter.  All I can say is it does what it is supposed to do.  Two annoying issues:

1. Flushing the filter with a million or so cups of water.  I believe this is a common, necessary evil among all of the water filters though.  This does not affect my actual rating.  I just find it annoying and water-wasteful.

2. No instructions.  Fortunately, I had a vague recollection of the fridge sales person showing me where the filter is located.  However, it would be nice if there were some directions or reference pics, or even some sort of hint on the filter box.  I understand not all fridges are created the same way, but even some basic, generic guidance would have been helpful.  Fortunately, we figured it out.

My "annoying issues" do not change the fact that this filter does what it should.  I would buy this again.
