Product review (3 stars): Inexpensive replacement works great but beware of quality
This set of three worked perfectly.  The first one of three I have used went in easy, although I have to tell you that in the last set of three I ordered, one of them would not insert (and this was being done by a refrigerator repair man) because there was something a little off with the plastic fins on the part were the filter inserts into the frig.  Great for the price as long as they are not defective.
