Product review (4 stars): A little expensive but these work as advertised
I have been using these filters for my Samsung refrigerator for about 3 years now. I change them every 8-9 months (a little beyond the recommended setting.) I have never had any issues with leaks or problems assembling them into the refrigerator. I thought of trying some of the generic brand which are about 1/2 the price but if you read the reviews many people complain of leak issues and fit issues and Samsung tries to scare you by saying that using unauthorized filters will void the warranty. I don't know how true this or whether it really matters after the refrigerator is 3 years old+.

I bought the 3 packs for around $90 shipped on Amazon which average to a price of $30/filter. Like i said this is much more expensive than generics but much cheaper than I could find anywhere else on the web. The are a little expensive but I do recommend them.
