Product review (5 stars): Very easy install, and youtube videos give a good install ...
Put this in a Whirlpool Gold 36 inch wide refrigerator and it took care of the leak caused by the old rubber grommet that would get gunked up and prevent draining during the defrost cycle.  Very easy install, and youtube videos give a good install description.  Once the ice that had built up in the freezer drain was melted it has not leaked at all.  I wouldn't even think of buying another old style grommet to fix a leak, knowing that it would be a short term fix.
