Query: I got a defective one

This item went on back-order right after I ordered it. It took 3 weeks to receive it and when I did get it, it didn't work. Because I wanted to have one for a long car trip, I had to go spend $20 on one at Radio Shack because this one that I ordered did not work and arrived WAY too late.
