It was a very easy switch to replace the water filter on our Samsung refrigerator. Since it was my first time switching the water filter I thought I should read the instructions before I attempted the switch. Everything went very smoothly and as long as the wife is happy, well everything is good. My wife did a great job on the choice she made with the purchase of the refrigerator and now it's my job to keep it in great working condition. I would recommend a factory replacement if for no other reason than the piece of mind.
