Product review (1 stars): Don't Cheap Out - Buy the Real Thing!
I ordered these as a compatible replacement filter for my Samsung refrigerator. We had issues with water pressure and found that I had to remove and re-install the filter every few hours to maintain water pressure. After several days of this, we ordered the Samsung official filter and continued to have problems.

After having a repairman come out, we found that the filter head was damaged - it was likely going bad anyway, as apparently that is a Samsung known issue, but the repairman confirmed that these filters are not truly compatible and using this one officially broke the filter head.

My suggestion is to save yourself the $400 repair cost I'm now paying, and just pay full price for the Samsung filters.
