This is an excellent replacement in my opinion for the baffle that is included with the insinkerator Evolution Excel disposal.  It is not as quiet, but still quieter than my previous disposal.  It is vastly better at letting the contents of the sink flow through to the disposal without having to shove everything through manually.  I would have given it 5 stars but it does appear to allow some splash-back, but at this point it is a welcome trade-off.
