Product review (4 stars): Fixed my "slow flow" problem...
I hesitated to replace the filter on my new GE Profile refrigerator when the indicator light came on (life-long procrastinator) until the water flowed to a dribble and the ice cubes were few and far between.  I ordered the single 1-pack product just to make sure this would fix my problem.  I received the product in just a few days, followed the directions, and had my "slow flow" problems resolved immediately.  The installation took about two minutes and now my 'fridge is as good as new.  I am going to order a few more to have on hand before the sales tax goes in force in Texas.
