Phat steam. I prepare the meal home from work, eg vegetables in the bowl # 1 (carrots, broccoli, potatoes, etc.), fish / chicken / turkey in the No. 2 and tomato / endive / zucchini in No. 3, I program the cooking time (20 minutes) and the delayed start ... and I'll do it over until the cooker rings the end of cooking ... do not worry, it maintains to warm for one hour. Not a bit of grease used only spices. A salmon steak with dill sprinkled a slice of lemon, some berries is a treat. Cleaning is no problem while disassembled. I have just one remark on the cover, it is not perfectly suited to the bowl No. 3, it does not fit properly ... and despite that, I will not hesitate about purchasing this product .
