I've had the same problem you see here in every review. The disposal is super quiet with this baffle, but the sink is constantly backed up due to it causing an air lock. If you take the baffle out or force it open it then works fine, but having to stick your hand or another object from the sink into the baffle is just not safe at all in my opinion. This product needs to be redesigned and replaced! I'm much less concerned with the noise it makes versus having my sink backed up all the time.
