Product review (2 stars): Does not fit tightly on Kenmore
This is supposed to be able to replace a Kenmore 9990 filter, but I found that it did not quite fit for my Kenmore 7901 refrigerator.  It turns a bit, as if it was going to lock in place, but never actually locks.  And since it fits loosely into the compartment, it could easily be bumped out of place and I'd end up with a leak.  Unfortunately, I just don't feel confident that I won't come home to a small flood should the icemaker turn on automatically and the filter is loose.  The water tastes OK, although doesn't seem to taste as good as with the OEM filter -- honestly, it doesn't taste too much different from the tap, and I have tried flushing some water out first.
