This thing is NO JOKE the easiest thing I've ever used in my life. Pretty sure it's idiot proof. And I'm an idiot in the kitchen. I love hard-boiled eggs, but I'm the kind of cooking-illiterate person who can't even boil water right. So I bought this puppy, read the directions carefully, got 6 eggs, and in 15 min, the buzzer went off and VOILA! Hard boiled eggs! I put them all in a bowl of ice water right after the buzzer went off, just for a minute or two (That was a tip in the instructions). That really made the shells come off easily. In one piece even! It was a joy to make these! They were perfectly cooked, nice and yellow in the centers, tasted awesome. I'm gonna make a bunch more and use them as quick snacks. This appliance is so great and cheap! I couldn't believe how well it worked. It's really small and all the pieces are plastic or metal, but it works like a charm, so who cares! A+++++ Highly recommended.
