Product review (4 stars): Works, with some modification.
Product is supposed to replace DA29-00003G but I have been using a DA29-00003G replacement filter for some years and this filter does not fit my Samsung refrigerator without modification.  Please see attached picture of the old, correct fit filter from the same manufacturer. With a utility knife the notches can be easily modified to fit in my Samsung refrigerator (trim some across the upper right notch, and lengthen/decrease the slope on the bottom notch - this only needs to be done on 1 set of grooves (there are 2 on alternate sides), you can ignore the other set!)  The plastic notches are very soft plastic so this isn't much of an issue, just an annoyance.  The price on these is great hence the 4 star review.
