This is a must have with the seal on the lid and the easy instructions to cook perfectly.  We had pork ribs last night and they were excellent.  I just put them in the Black and Decker digital slow cooker and added some onions and spices.  I programmed it easily. and off i went with my day.  with the new lid design, the whole house did not smell and just the kitchen.  I would definitely recommend this to others.
