Product review (5 stars): and now I have nice whole cubes
Yep.  This fixes the "crushed ice instead of cubed ice" issue.  I was a little skeptical, but before replacing this I always had crushed ice, and now I have nice whole cubes.  In another fridge, the problem was ice build up in the chute due to the door not closing, but in this fridge (Samsung RS277ACRS/XAA), the problem was this ice tray.
Installation videos are on youtube.
Nice cheap & easy fix.
