Query: DEFECTIVE DEVICE

THIS DEVISE WAS DEFECTIVE. IT GOT VERY HOT WHEN PLUGGED IN TO LIGHTER. I was lucky to discover this problem before there was a fire. I threw it away!!I just can not take a chance on a product that fails in this manner.A three dollar item just about took out my fifty thousand dollar navigator!!I went to fry's! Becare with these low cost devices that may stay plugged inwhile you are not in your vehicle ...do risk a fire!
