#3 How is the volume/noise of this machine while it is on and cooking? Is it quiet and soundless or noisy/loud?
To be honest, it's barely noticeable, and is rarely running long enough at a time to be bothered by the noise. I've had noisier dishwashers. Kinda like a loud microwave. Or a noisy air conditioner. Gently purring car engine. Not too loud. Not silent. Once you're used to it, you may forget it's on. So good thing it has auto-shut off. When the timer runs out on whatever you're cooking, it turns off. So you won't have to worry about burning your kitchen down because you got distracted.
