I order one of these for my daughter and myself and all I can say is that I wish I hadn't waited so long. My daughter told me that every time she uses it she is thrilled. She said that it's the best gift that I've given her.Quit searching for that key or having to turn off your vehicle engine in order to run back inside for that forgotten item and having to return to re-cool or reheat you vehicle.Great product and great service !!Let me add, that my husband is in the building business and could have purchased a different brand but decided to go with a well know brand and is very happy that we did. You won't be unhappy with the product or the company that is selling it.
