Product review (4 stars): Very narrow opening on quiet collar
Over all very pleased with this disposal. My main aggrevation is the quiet collar opening is so narrow that running water has trouble flowing thru it. The stopper has a pop up opening that I prefer to have in, just for that fact.  You have to really "push" the food thru the quiet collar.  It is removable so I end up taking it out to put food in.  But the disposal is very quiet with that collar on.  Seems to grind up the food very well.  It would be nice if the offered another collar with a little wider opening.
