My lifetime 4th disposal, and this one works great.  Seriously if you teach all users to scrap their plate in the trash, then rinse over disposal, disposals should last 15 years or more. Don’t put celery, egg shells, meat, or anything bigger than a crumb down any disposal. This one is missing a place to use a handy crank, but it has a reset button. My last disposal lasted 18 years, and it was the rubber seal that started leaking. The rubber seal! If you have to replace a rubber seal you might as well get a new Moen!!
