When I lived in Florida, I took a couple of Microwave cooking classes to "beat the Heat". I still cook in it occasionally, depending on the situation. Our first one was a first Christmas present from my parents. It was a Sharp, and lasted at least 10 years the first time. I am married to Mr. Fix-it which in MANY ways is a God send. However, we used that oven for about 20+years(married 36). I was wanting a more modern machine and he would replaced parts until he couldn't do it any longer. I was finally able to replace it with a newer machine, and have had 2 more since, as they make them to be "thrown away" once they quit working. I don't think any of realize how much we do OR do not use them until they break. I kept on going to the empty spot on the counter to heat my water for tea. Had to use the stove and more electricity to do so.
Happy Day!
