Product review (2 stars): May not fit your Samsung filter system
I did not have good luck with these substitute filters. After multiple tries to get it to 'lock' in, I finally had to throw it away.  I am glad I also ordered two Samsung model DA29-00003g filters at the same time.  They work just fine.  A little pricey but worth the 'no hassle' experience.  I will go straight to the original filter first next time.
