Product review (1 stars): Don't buy Samsung.
The filter does not fit, although the part number is the same.  From previous posts, Samsung changed the design.  WHO DOES THAT???!!!!!  Because I bought three filters in March of 2016, I cannot get reimbursed the approx. $90 that I spent for them.  Along with other issues with my Samsung refrigerator leaking water below the crisper drawer with apparently no fix.  (Already tried fixes that were on the Internet.)  I will never buy Samsung again.
