It doesn't cook your food, it just warms it to the perfect temperature. No smell while it's warming, either. I bought one for each of us. Highly recommend
Bought this almost a month ago for me and my boyfriend and we love them!!! He's a warehouse manager and I am a truck driver so we use them at least 3-5 times a week!
It's nice to be able to heat up the food at my office desk and eat whenever it's ready, but it seems the heat dries up the rice close to the side of inner pot a bit. The lid takes a little effort to line up and screw in tight.
