The alert tone is poorly designed. If you leave something in it, the oven will beep every minute to remind you. If it did this once or twice, that would be fine, but it does it FOREVER! What if you decide you want to take a nap instead of drink that coffee you put in there? NOPE -- Not until you've tended to your needy microwave oven! Defrosting something carefully? I hope you're not planning on a partial defrost, because at some point you'll have to go tend to your needy microwave oven! This is not a good microwave unless you enjoy having machines tell you what to do. Turning the tones off completely is an available option, but a very lame one.
