Product review (5 stars): Still working 6 months later
I got this after market replacement for my fridge and it works great.  I was a little leary of an after market part for a water system but went ahead with it anyway.  I had one problem in the beginning.  Every time I filled a cup the water would keep running for 3 seconds after I took the cup away.  I found out this was because of a bad pressure regulator on my house giving me over 120 psi.  Shouldn't have over 70 in a house in the USA.  Once I changed the regulator everything worked just as it should.  I guess the old filter was so clogged it wouldn't let enough water through for me to notice.

Six months down the road everything is still working just as it should.
