This is a fantastic item. I've read some reviews that said the "buzzer" does not go off. Perhaps that happens once in a while to an item, the person should deal with it like an adult and return it for a replacement. Mine does have a buzzer and it makes a buzzing noise when the eggs are perfectly done, and, the buzzing does not stop until I turn off the cooker! Eggs are perfect! Creamy yolk, whites are done. Amazing! You simly can't do it in a pan of water on the stove. I would buy again anytime and the price is fantastic for what you get. Would recommend this to anyone, friend, neighbor, stranger, anyone!
