My husband had a hell of a time installing this thing... but it works amazingly. I'll give it a 5 star rating because of that.. and the fact that its not loud at all. Part of the frustration was with our old disposal... which was an InSinkErator..I don't know which model it was though but he had a hell of a time getting it off.  He got so frustrated he left it till  the next day. And with this one he had trouble attaching it.  Just takes patience and it was worth it.
