I purchased it because of the price and the size. I like that it is 1000 watts because that fits in with my recipes and my experience in judging timing. Most of my cooking is on my two microwave ovens. The rotating plate tends to stay on track and the inside is large enough for my 6 qt. Corning casserole dishes. Though it cannot be programmed to change power levels in the middle of cooking, I did not use that feature when i had it anyway.
