I've only had this garbage disposer installed for less than a week, but from my limited usage it has easily handled potato and banana peels, pineapple skins and cores, and apple cores (which I expected). But the feature which stood out most at first was how amazingly quiet this unit is. The unit appears quite robust, and one of the recent professional reviews which I came across states, "The machine is able to tackle tougher foods like beef bones and can easily manage the trash load of a 4-6 person household."
