About two weeks after getting unit it started losing power. Thirty days and it was taking five minutes to boil a single cup of water. I emailed Amazon and they sent me the 800 number for Panasonic. This connected me to an offshore service center and someone who cared less. I could hardley hear them less understand what they were saying. They said I would have to take the unit some forty miles away and have it serviced. During the conversation they asked if I had unplugged the oven and if it failed every time I tried to use it. I gave up on the conversation. I recontacted Amazon and they issued a RGA and free return shipping.
