We replaced an Insinkerator model which came with our home when we moved in back in 2008. This model is higher HP and better technology and best of all quiet. It was easy to install and has worked very well on all foods we put down it. (The only things I won’t grind up are bones (though manual says it’s okay); shrimp shells (bad prior experience); and corn silk. All other food gets chopped up like it should and no complaints!
