Product review (3 stars): Buyer beware, they may not fit your refrigerator without modification!
Samsung engineering needs to fix these filters! Upfront, once you get them installed, the filters are great. They filter well (cysts, chlorine taste and odor, particulates (Class I), lead and mercury), the water tastes good, etc. And they meet all 3 NSF water filter standards, which many (most?) of the cheap replacements do not.

Now the MAJOR con: Without modification, these filters may not fit your Samsung refrigerator, even though they are brand-named by Samsung and are a 1 for 1 replacement for the DA29-00003G filter. There is a small design flaw with the teeth around the neck of the filter that interferes when trying to install on older Samsung refrigerators. By older, I mean only a year or two. I suspect Samsung brought the product engineering in house or outsourced the manufacturing to a new vendor and they did not produce a perfect copy of the original. Unfortunately, the damn things don't fit without trimming a little bit of the plastic from the teeth. At least I can tell you they don't fit without major force. I applied a lot of force, up to the point where I was afraid I'd break the filter mount in the refrigerator and could not install it. With a little bit of modification (trimming plastic), I was able to get it to go in. Several of the older reviews have pictures that show you how to trim them to fit. That I HAD to trim them to fit is an unacceptable failure on Samsung's part and the reason for only 3 stars.
