Product review (5 stars): Easy install, great noise abatement
As advertised, the new baffle installs with no effort.  Just pop it in place!  Be sure to remove the remnants of the old baffle first (I used a utility knife with a fresh blade).

The sound baffling is amazing, better than when my disposal was new and had an intact baffle.

Lastly, removing the baffle for cleaning is easy, just pop it out!
