We use this product so often that we bought one for our daughter. It has an efficient circle of heat which prevents food from burning on the bottom, has a rack that keeps food off the bottom, has a temperature control and has a removable porcelain pan that is easy to clean. I either use a cooking bag with added liquid or cover the meat with liquid. I cook anything from pork chops and roasts, beef roasts, small hams, chicken and more. It is my favorite appliance!!!!!
