I haven't used it yet, but I tried to heat it up and cool it down just to see if it works and it did!  My children attend Ohio State University which is only 2 hours from our house and I am looking forward to bringing them home cooked meals when I visit! It will also be nice to make a Costco run and then cart it down to Columbus for them!  I love that both cords for the car and home are included.  I just wish they's make a cooler that is more square than rectangular and it would have a larger holding capacity.  But I am happy with this purchase!!!
