I am absolutely satisfied with this microwave. It is by far the best one I've ever had-and I have experience with several brands. I love the food sensor feature it has along with other features that were not on previous brands. I definitely love that it has a child lock which is wonderful. Also the "Eco" mode that is very useful in energy efficiency especially in this tough economy knowing saving is very beneficial. I have 4 other items that are Samsung brand and I have not once had an issue with. Kuddos to you Samsung!
