Here is another kitchen appliance that can replace multiple cookers. The Wolf Gourmet WGSC120S Programmable MultiFunction Cooker can work as a slow cooker, rice cooker, and sous vide device. It can cook up to 18 cups of white or brown rice.
The device has a 7 quart stainless steel tri-ply vessel. It can saute and sear food on low to high temperature settings.
