I've had a nuwave for a year. It works well and is very easy to figure out how to use. It comes with booklets and recipes. It cooks meat and crisps things up beautifully. However, two problems: it is a bit difficult to clean, though it can go a couple times without cleaning the dome as long as you wipe out the pan and the space under the pan between uses. Also the plastic dome now has two cracks in it, large and getting larger. I believe they now have a glass dome for it. If you have the $ and the counter space, I'd say try one. My microwave is long gone, and this defrosts just fine. As you can see the dinner inside just fine, you can gauge the doneness easily enough. However they do include a handy timing chart.
