Product review (2 stars): Going back to OEM filter after this one.
Wasn't a 100% match for my Samsung side by side refrigerator. I installed and ran the water to purge the system, and it immediately started leaking at the filter. I un-installed and re-installed and ran again and got the same result. I put the original filter back in and everything is running fine. After inspecting the teeth/threads that are used to tighten the filter, they are not a match to the original filter either. I'm not sure if that has something to do with it or not, but I also noticed the diameter isn't 100% the same either. Either of these might have had something to do with the leak, but I'm going to go back to the original manf. of the filter that came with the fridge from now on. This may work on some refrigerators, but if you have a Samsung RSG257AARS, I would look elsewhere.
