Product review (4 stars): Fine if your water source is safe enough.
We have an RF267AWEP Samsung refrigerator and replace the filter every 6 months. We used to re-order the original Smasung one for DA29-00003G  (Samsung DA29-00003G Aqua-Pure Plus Refrigerator Water Filter, 1-Pack), however for some reason the last one that came would not fit in our fridge. We noticed other people complaining about it. We called Amazon, and the rep mentioned there may have been a mismatch between the model display and the one actually in the box(DA29-00003F). He then suggested this substitute which was considerably cheaper. Reluctantly we decided to give it a try.
The good: perfect fit, no leakage (as some people complained), no taste/odor present. It is worth mentioning however that our local water is safe and free from odors even without a filter, although it does have is a slight taste of Chlorine.
Customer service, although we did not actually needed it is exceptional - they follow up with an email with instructions even before it arrived (faster than expected).
The bad - although it looks exactly like the original one, and supposedly made by the same company, the certification is inferior, and the supporting documentation is much less convincing than the original one. the original is tested and certified by NSF International against both NSF/ANSI Standard 42 and 53 (aesthetics and health hazardous substances), whereas this substitute states it filters "aesthetic effects" only such as chlorine taste, with no mention to actual NSF standard approval (ANSI 42).
As I mentioned above, since our local water is in fact safe this filter is usable for us in spite of its inferior rating. However if you are not sure about your water, you should probably stick with the original.
