Product review (2 stars): SSSLLLOOOWWW filters
The good news is that they fit.  And presumably, they filter.  But this thing takes its sweet time filtering.  Water dispenses about half as fast as the OEM filters.  I'll be picking a different brand filter next time.

I'm hoping this was just a one-time issue, but when I installed it, an o-ring popped out of place.  The result is that while I was flushing the filter, I ended up flooding my refrigerator.
