First of all, this oven could not run with any other appliance on the same line without tripping a circuit. OK, it's powerful. But then it decided to die on us just a month after the manufacturer's warranty expired! How convenient. We ordered this through Amazon and I don't know if it got damaged in the shipping, but a microwave shouldn't die after a year. We have an old microwave at work that is utilized constantly by a rather large staff and it's amazing this thing does the job. So there is no excuse for this appliance to have such a short life.
