Product review (4 stars): Good filter for Kenmore frig
Seems to be working well, it was a little tricky installing because I thought you had to twist it to get it seated.  But, apparently was necessary.  Only been in a little over a week now, but don't see any problem so far.  Price certainly makes it worth trying.  Delivery was as told to expect and packaging was done well.  All in all, a good buy.
