Bought this for my husband so he could have some hot lunches especially in this very cold weather.  He would put anything that needed heated on his dash and let the sun warm his food for lunch.  I saw this and thought it would be worth the try and it was.  He says it works well and likes it.  Some things take longer than others, but you learn that as you use it.
