This is a great little cooler. Is the perfect size for when me or my wife and I travel. It does a very good job cooling down beverages and keeping food cold. I have not tried to use it to warm food but the cooler work very well. Even better if you pre-heat beverages before you put it in the cooler. I recommend a 12 volt to AC adapter to be able to take it with you into a hotel room or your home. Overall we are very pleased with this little cooler. We have two sizes,  this one which fits perfectly behind the seat of A Car give easy access, and a large your family size when the whole family travels I personally like this smaller size because it is so convenient and easy to get to.
