Product review (1 stars): If you like the loudest chatter ever from your frig, buy these!!!
Right out of the box it chattered WORSE than the old one I took out.  I've found that usually when a filter starts to chatter, I can pull it out and put it right back in and it'll work a few more weeks.  Tried pulling it out and reinserting it and nothing.  Still chattered loader than I have ever heard in the past, EVER!!!  Junk is the only way to describe it!!  I went to Home Depot and paid $50 for 2 of their generic filters and they are perfectly quiet.
