Product review (5 stars): WSS-1 Perfect fit & replaces Aqua DA29-00003B
I had ordered the WSS-1 filter before and had no problem with it. I MADE THE MISTAKE of ordering the Samsung Aqua Filter DA 29-00003G for my Samsung RS2556BB Frig. The 3G supposedly and was a match to the original DA29-00003B. This was not true for me. The 3G did not work on my refrigerator. The threads were slightly to the right of vertical whereas the 3B and the WSS-1 has the circular thread entirely vertical. I just got my new shipment of the WSS-1 and it fit perfectly.

Good Luck!
