Product review (1 stars): Knockoff
I bought this filter on April 2015 because it was cheaper than the one I got from Sears.  But it was very difficult to turn to lock it in place. Then I decided to order directly with Samsung Company. I noted on the outside of the box I got from Samsung that it has a stamp " Samsung water filter- Genuine Water Filter".  It is so much easier to turn to lock it in.
