Product review (1 stars): very disappointing
I followed the instructions as to pre-soaking the filter before installation, etc., but the water flow is incredibly slow with this filter.  I mean really slow.....just filling up a glass of water takes quite a long time.  Most disappointingly, FIVE phone calls and messages to the company that claims to have a satisfaction guarantee went unreturned.  Totally unacceptable.  I hope a prospective customer reads this review and looks elsewhere because once you buy these, you're stuck with them.  Complete waste of money.
