Product review (4 stars): Time for a change?
Works as advertised - replacement water filter for our Samsung refrigerator.

Easy to replace - open the front doors, rotate the old filter about 90 degrees counterclockwise and pull it straight out. Slide the new one into the opening, push in and rotate back to the right. Close the door and then press and hold the "alarm" button for 3 seconds to reset the "change filter" light.
