Query: *** Blew up in microwave. What a mess! ***

We've had this product about a month and have been very happy with it. But, today, after putting in 4 new, organic eggs, it literally blew up splattering eggs all over the inside of the microwave. (With such force that it blew apart the cooker.) So, beware.
