Product review (1 stars): BLEW UP IN REFRIGERATOR
This was the 3rd water sentinel filter I bought, and followed all of the instructions carefully.  I thought they were a great deal, but this one blew up in my face upon installation.  Water and charcoal like substance sprayed everywhere.  I cannot get another filter in, so it also damaged the attachment port on our refrigerator and I have to call a service guy.  I will NEVER buy one of these again!
