Twenty year old Sunbeam slow cooker.

Sunbeam HP3510.
Yes it's beaten to hell and back. Still cooks good food.

People asking about if your tiny blemishes or scrapes from a spoon make your appliance unsafe, it's fine, this is what mine looks like (contrast up to show the wear).

Taco meat, soups, classeroles, mulled wine, puddings, roasts, brisket, curries. They've all been cooked in here. Hit the ceramic with a scourer or into the dishwasher. I've run this thing for three days straight making ox tail and barley soup.

You'll be fine. Enjoy your slow food.
