We have been quite happy with the warmer until last week. We plugged it in and 5 seconds later it was smoking and burning at the car adapter outlet. My husband right away pulled out the burning plug but it already melted and a metal piece of it stayed int the outlet causing an electric short. So we were not able to restart our car until it was removed by a mechanic. Save yourself the experience of standing on the side of the road with a hungry baby on a rainy day due to this product.
