Product review (5 stars): Works just like OEM.  Inexpensive alternative to costly Samsung filters.
Fits and works in my Samsung RF263BEAESR French door refrigerator perfectly.  I don't understand some of the negative reviews here, but I do know that these filters work perfectly in my Samsung and are an inexpensive replacement for the more costly Samsung filters.  Maybe others got the wrong filter or they received defective filters.

Pros:
Inexpensive
Fits perfectly
Works great

Cons:
None
