Product review (4 stars): Good Filter
I just installed my first filter on our new fridge.  It was easy to twist to the unlock position, but impossible to pull out by hand.  A 12 inch pair of channel lock pliers with a firm tug popped it right out!  After turning the water supply back on, I drained out about a gallon of water (vs the 6-7 gallons the owners manual recommended) and the water was perfectly clear!

These are good filters!  I checked mine a half hour after installation and no leaks!!!  :-)

I gave it 4 stars, since I had to use a tool to pull it out of the fridge.  (I think the engineers could put some knurls on the gripping part to make it possible to pull it out by hand.)  The first one lasted 6 months before the red filter light came on.  I suspect we could have used the old filter a few more months, since most of the time it's only my wife and I using the filter.
