Product review (1 stars): Waste of time.  Not the same as Samsung.
I am a strong male who, no matter how hard I tried, could not get two of them to twist into place at all.  Some piece of the plastic was not making it around.  Says it's a replacement for Samsung DA29-00020B, but it is slightly different.  I didn't even bother with the third.  Sending these back.  Don't waste your time or limited patience.  Buy the Great Value brand for $21.  I have had no problems with them in the past.  Just thought I could save some more money here.
