You throw a bunch of food in them in the morning, turn it on low, and come back 10 hours later and your food is done. It's always cooked to perfection and no slaving away over the stove and oven to achieve it. It's almost like magic. The convenience of a crock pot is unsurpassed. You get homemade food, that is prepared when you walk in the door and all you have to do is plate it and eat it.
