We are very happy with the Evolution disposal. It is MUCH quieter than the Badger model we replaced. The water running in the sink is more noise than the disposal.

It was fairly easy to replace. I used all the mounting and piping from the old disposal. I gave it 4 stars instead of 5 because I had to remove the power cord from the old disposal and attach it to the new disposal. For the much higher cost of the Evolution; you would think it would include an ALREADY attached power cord!

Reminds me of the olden days when you have to pay extra to get a rear bumper on your pickup truck.
