Product review (1 stars): Flow rate cut after a week
Bought this filter because of all the good reviews, but haven't had the same experience.  Maybe I just got a bad one, but within a week of installation, the water flow rate cut in half after just a couple of ounces.  Took the filter out and shook it to see if the problem was the filter or the fridge line.  That fixed the problem for a couple of days then it happened again.  Have now done that multiple times and the problem has gotten progressively worse - now it only lets out about one ounce before it cuts off and shaking it only fixes for a day at most.

Installed a new one from Walmart - have used their Great Value brand for 2 years with no issues - the problem seems to be gone so I know the issue is with the filter not my fridge.
