They aren't worth the powder it would take to blow them to hell.  Don't believe what  you see/hear on tv about these things.  It shows some black woman saying how the eggs dance around in the pan.  Really?  Mine were so stuck to the pan that by the time I got them off, the yolks were broken and fried hard as a rock.  I like my eggs with soft yolks as long as the white is done and fully cooked.  Having butter in the pan would have been a good idea even though they tell you not to do that.  It's all a big damn crock. WASTE OF MONEY.  If I had the energy I would box them up and send them back but I have already cut up the box and put it into the trash. I also didn't get the knives that were promised in the ad.  A TOTAL LIE from this company.  I sent them a scathing email but haven't heard back.  Imagine that.
