Purchased this to replace an older model that had begun to leak at the connecter, which had cracked and could not be repaired.. The plumber had to reconfigure the piping for the connection, which upped the price of installation. It is quiet, however, my older model had a baffle so I wasn't staring down into a deep abyss of a garbage disposal. A baffle cannot be used with this model due to the depth of the cover control unit. Unless I leave the cover control unit in place, I am looking directly into the disposal. I seem to have to run it longer or even twice clear the unit of food debris.I cannot clear it entirely of food particles. It does the job, but nor as well as the model I replaced.
