Product review (5 stars): It fits, it functions and performs as expected
Fits into my Kenmore fridge filter slot without incident. Water tastes fine. I will update the rating to a five if we can make it to the 6 month mark in using it.
REVIEW UPDATE 7/20/2017 : made it without incident to the replacement. Works fine. I placed a re-order on the item.  Happily, I moved the star rating from a 4 to a 5.
