It’s safety feacher is why I chose this one. No way to chop up something unintended like fingers. Quiet and efficient too. The wall switch can stay on without this continuiously running. My insinkerator hot water faucet is plugged into the same outlet under the sink. The switch controls both on the same outlet. At the end of the day I turn the switch off and both appliances are off. No way for little children to hurt themselves with either appliance.
