Product review (1 stars): It failed
This is smaller than the original equipment.  It seems to let the water through faster, which I assume means less filtering.  It has clogged once in a month or so, but I just pulled it out and put it back, and it worked again.  I might update this later if I find out more about it.
UPDATE:  Since I wrote this original review, it has clogged, stopped the icemaker from working, leaked, and had the other issues some people have complained about it.  Unfortunately, it's too late to send it back.  Just don't order this.
