Product review (1 stars): Is not an exact replacment!
Would be zero if possible.  Returned it - did not work. It says it is a replacement for DA29-00020B but based on results I would disagree.  Difficult to install, then leaked. Tried multiple times and yes I did lubricate the o-rings, but still leaked. Next try was with the Filterlogic brand replacement filter - worked like a champ.
