Product review (2 stars): The description for the item changed.
I did receive one genuine water filter for my refrigerator and it worked fine.  But what I ordered (and what it stated on my invoice and on my order confirmation) was a "3-pack of ..."

I tried to contact the vendor, no response.
I tried to contact vendor through Amazon resolution web page, no response.
I filled out an Amazon claim, no response.
Amazon refunded my money.

So although the filter I did get was fine, the vendor needs to work on their customer service.  I am satisfied with what happened, but still it would have been more fair if they had just refunded me 66.6% of the money I paid, or had sent me two more filters and not refunded me anything....
