Product review (5 stars): Worked like a charm
This just slips right in from the top and fit my insinkerator 777ss perfectly. I left the old mangled one in place figuring extra flaps won't hurt and since this sits farther up, it wasn't an issue when installing this. It cuts down a bit on sound and reduces spray. We haven't had any issues with slow draining. Overall it looks much better than the old crummy one.
