I am not unhappy with this microwave, but I found that although it is rated 1000 watts, it seems underpowered compared to the 1000 w. unit it replaced. Once you get used to the controls, it performs quite well. My old unit had a steam sensor, but this one does not. I don't find that to be a problem. For cooking one, two or three minutes, it's just one button press, and I like the +10 second and +30 second buttons. It would be nice if you didn't have to press the "cook time" button before pressing them, but when cooking, it's easy to add 10 or 30 seconds with one press. I'm giving it 4 stars because I wish it were a bit more powerful.
