Product review (1 stars): Slow flow.
Our experience with repeated versions of this filter is that the water flow diminishes significantly.  I've also had to replace the water pump twice now.  Finally switched to a water filter from HDX and the pressure is back to normal.  Note, I did try the trick of soaking the filter in water to remove all the air prior to installation.  Worked initially, but after 24 hours, the slow flow/resistance was back.
