I had to replace our previous unit and this was the best deal and readily available. The controls to both the Microwave and the Oven are easy to use, HOWEVER, the bell or chime to indicate cooking time is over is barely audible, even when you're in the kitchen, and only rings once. We had to get a small battery operated timer and hang it on the unit, but it's not a big issue, just a little annoyance that for over $2000 you can't tell when your food is done.
