This is a miniture crock pot, but its purpose is to warm your food. You can warm it right at your desk. Its beautiful. Now it has a 20 oz container. The bowl may look small, but it's all in how you pack your food. Rice at the bottom, vegatables on the side, if you have meat remove it from the bone and place inside the container. And pack it down. Put the inner lid on and screw on the top. Put it on about 45 minutes to 1 hour prior to your lunch break and your food will be piping hot. This is good for people who have short lunch breaks and want to utilize their full 30 min of 15 min breaks. It avoids you having to wait for your turn to use the microwave at work. I recommend insurance only because, if it breaks, you are definitely going to want another one asap. A regular lunch bag won't do after you use this. The cord wraps around the bottom for easy storage. This lunch box is compact and fits right inside my small back pack. You can't go wrong with this. The price is amazing for the quality of the product.
