This is a great slow cooker. Not being much of a cook, it came with a recipe book which was a real necessity for me. I love being able to throw in a bunch of ingredients and have it turn out tasty and well done, especially after practically no work from me. Time to Heat Depending on the settings you require, the time it takes to heat is just great. Cooking Performance The cooking performance is fantastic! I follow the recipes as I have no imagination. Everything always turns outs perfect. Ease of Cleaning The unit cleans beautifully. You just take out the middle cooking cylinder, put it in the dishwasher and wipe down the outside of the unit. Ease of Use Couldn't be easier. Follow the settings in the recipes and you won't go wrong! Design They designed the unit very well. Not only does it work well but it looks good on the counter. Durability I have owned this unit for over 5 years and there isn't a mark on it. Mind you, I do take care of it but it is made of such strong material that it would take a lot to mark or scratch it.
