Product review (2 stars): Poor fit for my refrigerator
I verified the correct filter (WSW3) for my refrigerator with Water Sentinel  before ordering 2 for my Kenmore Elite refrigerator (model 106.74206402). Upon receipt I noted that the rectangular base of the filter was narrower than the original filter and did not fit securely into the device that holds it in place. I called Water Sentinel about this and the rep assured me that it would still work. She further stated that it had to be smaller because of the patent on the original filter. I believe that the narrower base doesn't allow the the forward part of the filter to seat correctly. In the 3 weeks since I installed this filter it continues to leak. For my Kenmore refrigerator  this filter was not a good replacement.
