Audiovox D1708PK 7-Inch Ultra Slim Line Portable DVD Player with Bonus Pack
Only lasted one trip for me, too
Bought this because it looked like such a great deal.  After reading bad reviews, I tested it before giving it to my daughter for her birthday.  No problems.  Used it for the first time on a flight.  No problem.  Changed planes, and it would not work on the second flight.  Recharged battery, tried again, and the disc will not spin.  Returning to Amazon because it is still within 30 day return time.
