Product review (1 stars): Not a good fit
I had to return this product because it was not a good replacement for the Whirlpool 4396701 refrigerator filter.  The filter was too long and not as thick in diameter as the Whirlpool model.  the filter was too long and was unable to lock the filter into the refrigerator.  I removed it, packed it up and returned all 3 filters.
The good news was, it arrived when it was supposed to and Amazon.com allowed me to return the filters without any problem.
