Product review (3 stars): Beware:  Match your disposal flange, not your disposal.
I'm sure these are a fine product *if* you have an InSinkErator disposal flange.  The brand of disposal is a red herring and *not* the essential element, the brand of flange is.

I have an InSinkErator disposal, so I thought this baffle would fit.  I spent quite a time struggling with it trying to make it work.  Then I found out I had an Opella disposal flange over my InSinkErator disposal so I needed the Opella baffle, which is slightly smaller, instead.

As I say above, match to the disposal flange and not the model of the disposal itself.
