Product review (1 stars): New design restricts water flow, very annoyning.
Beware.  The manufacturer of this filter has redesigned the end fitting I assume due to silly EPA regulations on flow rate. The hole on the end used to be ice pick sized, it is now large paperclip sized. You will not get the same flow rate you were used to with new filters. This is not Amazon's fault. Be prepared to waste parts of your lives filling water glasses.
