Bests & Worsts Reviews from Amazon

So I bought this portable DVD for my dad for his birthday. I chose this one because it had the longest battery life of any other option on the market at the time, and had the best array of features and support (plus it looks really nice). We received the device, and my dad let's it charge overnight, as instructed. He tests it out the next day by watching a video, running on battery charge only. It lasts 3 hours. He does the same test the following day. Lasts even less time. We call customer support. Here's the story they tell: In order to achieve a 6 hour battery life you have to use headphones, not the external speakers and run the display at -5 brightness. Just the clarify, -5 brightness is BLACK. There is no picture at this brightness. So essentially, you're listening to the sound track. This is a glorified CD player at this point, and even then, the battery life is crummy. We then write a letter to the chairman, only to get a letter back from a director of marketing telling us exactly the same thing. This product, likely a great DVD player, has been ruined by Panasonics Marketing department. The fact that the DVD player explicitly says 6 hour battery life on the package, multiple times, and no where indicates the need to drop the display to -5 brightness (except in the manual) and yet doesn't even come close to that level of performance is terrible. I've been a huge supporter of Panasonic products. Saying they're the underdog and under rated. Well now, I'm changing my tune. You know, it's ok to be wrong. Admit the package and marketing of this product are wrong, and don't tell me the customer, who supports your job and business and technology and brand, that I'm wrong, or that I have to use the product in such a way that it doesn't even make logical sense. So for those of you thinking to buy this, keep looking. It's not what it says it is.
