Product review (2 stars): Water filter
We have a Bosch French Door refrigerator which uses these filters.  When we first install the filter, the water flow through the door is great.  In just a couple weeks, the flow diminishes to the point that we do not use the "Water through Door" feature.  The filter life is 90 days so one would think the flow would be good for that period of time.  I ordered three filters and replaced the first one after a couple weeks and it functioned the same with diminished water flow.  The filters are expensive so this becomes a real cost disadvantage.
