Not a bad device if you're buying it to play DVDs when travelling. I use it with a Samsung Netbook and find it almost perfect. An unexpected bonus was its ability to play multi region DVDs, something I wasn't expecting without downloading a hack. I'm not sure how it slipped past the big movie studios, who try to discourage that sort of thing, but slip past it did.
The only downside is that it doesn't handle playing double sided DVDs well, if at all. So if you have a lot of box sets that use the cheaper two sided DVDs, expect to be able to watch only the top side using this player. A strange oversight, and not one you'd expect, considering all DVD players these days can play double sided DVDs.
