Summary: My trusty Mintek MDP-1720 started acting up (and is no longer manufactured, apparently) so I started shopping for a new one. I went with this one, despite the warnings about picture quality, since 1. it was 9 inches, 2. I got a good deal where I bought it from, and 3. it's Panasonic and I've bought good stuff from them in the past. Sadly, I have been spoiled by Mintek.
Summary: This dvd portable functions great. It has everything you need and the swivel screen that allows it to lay flat is awesome. However, do not purchase this dvd portable if you care about how good the picture looks! The screen resolution is absolutely terrible! Especially in comparison with some cheaper dvd portables from Mintek or Toshiba.
Summary: I originally had the Samsung DVD-L75 that is a 7" screen with a 4.2hr battery but had some problems with the DVD drive so I thought I'd "upgrade" to the Panasonic. I'm so disappointed with the picture quality that I'm thinking of exchanging it back for a new Samsung. The picture quality on the Samsung was very bright and sharp that it rivals my Toshiba HDTV. The Panasonic looks like an old 80's tv where you can see the little squares that make up the screen.
Summary: I love everything about this unit except the picture. The adjustable screen, the color saturation, and the battery life are great. But if a DVD player doesn't deliver a good picture--and this one doesn't--then the only reason to buy it is if it's competitive on price. This one is expensive, and there are less expensive units out there with better pictures. I'm returning mine. If you're not picky about the picture or it's for your kids, it might be okay.
