Product review (5 stars): Easy Install and Cord is already wired! Great Product!
Except for the delay in shipping which was probably due to Christmas holiday, I am very happy with this disposal. Same and better than buying it at Home Depot because I could use my Amazon gift cards and Amazon  credit card.  Easy to install because I already had the upper portion in my sink as I was replacing same brand.  You just push it up onto the ring slots and turn to lock it on. Plus this model has the electrical cord already attached!  no install of that needed.  Home Depot did NOT offer this model at the time.  BTW I am a woman of petite build, and I was able to install it. My husband stood by to hand me the tool, and to help with the tightening (a little bit of muscle is needed). Take my advice and use a small box or step stool to support the bottom while you maneuver this into position to line up with the drain pipe and DW hose.
