What more can I say other than the head line? This replaced a Waste King that was noisy with a rubber insert in the drain that kept coming loose and falling into the disposal. Very annoying. 

The InSinkerator works unobtrusively and just does it's job. Just like the one we had in another home that after 20 years still works great. Can't imagine why you would spend more on any other brand or a more expensive model.
