This prpoduct was SUPER easy to install, especially because I was replacing an plug-powered existing unit.  I will never again install a garbage disposer without a duplex receptacle - it makes replacement SO EASY!  The disposer matched my existing Insinkerator to a T, and was in and out in 20 minutes.  It works great too.  Chews my solid waste up with the best of them.  Worth every penny!
