This seems to be a high quality product at a very reasonable price.  It cooks less expensive cuts of beef (stew meat, chuck roast, corned beef) to mouth watering tenderness in a fraction of the time required in either an oven or slow cooker.  It quickly cooks two or three pounds of chicken for salads, sandwiches, or freezing.  Cook a pork roast with your favorite barbeque sauce in 30-45 minutes and enjoy pulled pork sandwiches infused with the flavor of the sauce.  This would be a great tool for the cook who likes make- ahead meals and stocking the freezer for quick-reheating weekday dinners.  Get the stainless steel model to avoid the reaction of aluminum to acidic foods.  Eventually you will be glad you did.
