Product review (5 stars): Great replacement sink baffle - easy to replace
Basically this is the rubber thing that sits in the middle of your sink where all the water and other kitchen refuse go down into before you "Insinkerate" it. The one I had was falling apart, so I bought this as a replacement.  I just pulled out the old one, and pushed in this new one, and everything works well.  The only thing I did notice is that because the four plastic flaps you see on the baffle is a bit stiff, the kitchen refuse like bits of veggies or fruit skins do not go down easily into the Insinkerator, and at times I would have to push them down to grind them.  On the other hand it does keep things like spoons and forks from falling in easily!
