Product review (2 stars): Disappointed
One of the three was defective.  The thing we all noticed was how slow the water comes out compared to the original filters.  The other painful reality is the water speed/pressure slows with use.  The original filters don't do that.  Filling a small glass is not so noticeable.  Filling a spaghetti pot with the slower stream is torture.  The money we saved (substantial) was NOT worth the time we lost.
