This baffle came with my Evolution Essential garbage disposal and I honestly have mixed feelings about it. Yes it does make the garbage disposal quieter by draining water slowly which covers the drain hole with water to quiet it down. But at the same time that's an inconvenience when im washing dishes. I often find myself removing the baffle when water starts filling up my sink. For me, the decibel level is not a concern, I just wish it drained better. For as much as the upper end garbage disposals cost, they should have included a choice of baffles.
