We replaced a Badger 444 (4-yr warranty) with the Essential (6-yr warranty) . Installation was fairly easy since the electrical (hard wired) and plumbing were already there. I tested it pretty hard for the first use and I was pretty impressed with the abuse I gave it.. (I had a fridge full of food that needed to be disposed of.) And it is quiet enough that anyone can have a normal conversation when it is turned on.
