Product review (5 stars): After dealing with noisy garbage disposals that broke down in apartments
This baffle was the right choice for my newly installed InSinkErator Pro 880.  After dealing with noisy garbage disposals that broke down in apartments, I have only bought the InSinkErator disposer and its matching products.  I use my disposal very lightly and have not had problems with the flow through this baffle, but I understand why some people might not like the small opening.  If you save bulky items for the regular garbage and use plenty of water the disposal is running, you will like this baffle.

After each use, I shake it out and invert it, placing it loosely over the drain so it can drip and dry out.  Doing this after every use prevents build-up of residue so it is very easy to clean with a Lysol wipe once a week or whenever needed.
