Initial DVD-9510 Portable DVD Player with 4-Inch Screen
Frustrating and not worth the money.
I bought this less than a year ago and I've been trying to take it back ever since.  I've sent several e-mail messages to the manufacturer and they have never responded.  I've also sent Wal-Mart.com several e-mail messages and they won't respond either.  This unit overheats within an hour of play.  It won't play some DVDs at all.  It quits playing if you even touch it, then you have to start it up again and find where the movie left off.  It freezes at times and you have to start the movie over again.  It's terrible to take in a car with you, which is why I bought it in the first place.  You spend more time fighting the thing than watching it.  The screen is also hard to see, especially if you're in the back seat.  My kids complain that it's too dark, even at the lightest setting.  I wouldn't recommend it.  Save your money and get a nice, working player.
