Product review (1 stars): As far as I can tell this is either designed this way or it is poor quality control as expected from china
It fit as described, but the water flow was cut down to half of the flow.  I tried two filters with the same results.  As far as I can tell this is either designed this way or it is poor quality control as expected from china.  It may be a bargain if you have all day to fill up a full glass of water.
