Product review (3 stars): 3 Stars does NOT represent the Quality of this item.  Just haven't used it yet.  But looks like it's the correct replacement.
The 3 stars have nothing at all to do with the product quality itself.  It is only because I've not yet used it and the request for me to review this came too soon.  I bought this in advance to have on hand for when it is time to change my current filter.  I wanted to be prepared with the correct replacement product after I learned that the Whirlpool model is no longer being made.  But it does appear I found the compatible product for my refrigerator. I will come back later and give a review after I've actually used it.
