Product review (5 stars): Despite negative reviews, this product is legit!
I was VERY skeptical of this product after reading several reviews alleging this was somehow a counterfeit product. Long story short, this product is just as advertised and works perfectly.

A few reviews I read mentioned that OEM filters are made in Korea, compared to this "counterfeit" which is made in Mexico. When I opened the box, the first thing I did was check to see where it was made. This product is indeed made in Mexico, so I was highly disappointed at first and fully expected to have to send this back. But I took out my OEM filter to replace with this one, and to my surprise, the original product in my refrigerator was also made in Mexico. After seeing this, I decided to give it a try. I listened very closely for any "strange noises" coming from the fridge that other reviewers said occurred when using this filter. Nothing. There were no strange sounds, no lack of water pressure, absolutely nothing happened, and there was no change to my fridge after installing with this Amazon product.

My only guess is that people are not choosing the correct part number for their refrigerator. Samsung doesn't make it super easy to find the exact model numbers of their units, so maybe this is the cause of the bad reviews. If you match your model number with this filter, you will have no problems with this product. Highly recommended, especially for the low price compared to local retail stores.
