Actually the review title should be "it warms!". This is a nice little oven that will warm food but you have to use it a few times to get to know how long cerain items will take to heat. Depending on if your food is frozen or just cold, it will take between a half hour to an hour to heat up sufficiently. It's a little smaller that I thought it would be but it's easy to transport. I use little tin pans and with a little planning, this product does what I need it to do.
