Product review (1 stars): Not a perfect fit
It did not fit into the Samsung frig that it was designed for.  It is slightly shorter than the HDX filter it replaced which had worked fine.  Seemingly because it was minutely shorter (though it could have been for another reason), it does not seat and water poured into the crisper.  Had to pull the expired HDX filter from the recycling bin and reinstall it to stop the leaks.
