Product review (5 stars): Refrigerator Water Filter
I bought this particular Water Filter because it was the one for our refigerator.  I bought the 3-pack so that I would have some on hand.  The installation was a breeze.  I followed the directions that came with the filter and had no problems.  Removal was a simple CCW twist of the canister.  Likewise, installation was a simple clock-wise twist of the new canister into the holder.  I prefilled the new canister with tap water, per instructions, and ran about a gallon through before drinking.  I have had no problems and the water tastes great.  I would buy from Amazon again, since they had a good price for the brand I wanted.
