We purchased this Evolution Essential only because the originally installed "garburator" died. I am not a fan of using the sink for disposal however, I am very impressed with how quiet it runs. In fact, it's seems quieter than the demo in the store. I almost have a hard time believing its working! It was easy to install, even for a novice like me. (with existing connections) We have not used it to grind up much in the way of serious food. Still, the proof will be how it holds up over time and by that I mean years. So ask me again in 2021.
