Query: Disappointing Unit

First I'll say that I have no one to blame but myself for having bought this unit - I purchased it sight unseen on eBay. I can't say that it does not do what it is supposed to - and it has survived several long car trips without problems. The DVD player has worked fine throughout. However, it does have one major fault: the display is simply not bright enough. It's OK in the house (provided you dim the lights). However, in the car the display is almost unusable. Even in the back seat of a minivan with dark-tinted windows I had to block off the sides with cardboard to make the display watchable.So the bottom line is that the unit doesn't quite fulfill it's promise. I would not recommend it to anyone. I would recommend that anyone looking for such a unit buy from a local store where they can return the device if not satisfied. My only compensation is that I paid considerably less than the average price for the unit I have.
