Product review (1 stars): The Samsung filter is an easy in and out rotation to the locked position
It does not fit the samsung RF28HFEDTSR refrigerator as was advertised.  The locking flanges at the top of the filter are about 1/16" lower than the stock filter, and once inserted will not allow the filter to be rotated into the locked position.  The Samsung filter is an easy in and out rotation to the locked position.  No way I'm turning on the water supply again with a filter that will not lock into position.
