Product review (5 stars): Works well - have used for a couple of years now...
We have ordered these many times since we got our refrigerator in February/March of 2010.  I have never had any trouble with them. We have two people at home all day who drink tons of water.  The filters last us around 4 months.  You can always tell when the filter is getting ready for a change as it takes longer to fill a glass with water.  You have to be sure to follow the instructions after inserting a new filter, and sometimes during that initial process, the dispenser will leak a little, but only during the process of clearing out the new filter.  I am guessing it has to do with the water pressure or something, but it has never leaked after that point.  It has never leaked from the filter itself.  My husband was very skeptical about buying these at first, so we tried just one and were happy.  Since then we have been buying the multi packs.  Our water tastes TERRIBLE out of the tap. With these, it tastes as good as bottled, for a fraction of the price, plus no waste from the plastic bottles!
