Installed about a month ago (March 2020). Replaced the big monster unit under the sink, when it started to sound like it was crushing rocks. I started to really reflect on how much food I sent down the sink. Coming to the conclusion that I do not need a monster garbage disposer, the GXP50C looked like a good choice.  This unit has been perfect for my daily use. The unit foot print is smaller so there is a lot of extra room under the sink. Was easy to install, basic plumbing skills or just read the installation instruction and you will be able to install the unit.  The sink mounting ring was also replaced (just use plumbers putty). Changed the electrical connection from hard wire to an outlet, which simplified installation. Also rerouted the waste line (drain pipe) to increase storage capacity under the sink. A very nice feature is the removable splashguard that can be washed from time to time.
