Disposable Player

Watch out!!!
The built-in battery cannot be replaced by any means. Here are some quotes from Philips customer support:
"We do not manufacture and sell replacement batteries for the unit."
"We apologize to inform you that the battery is not replaceable. It is an internal part of the portable DVD player and you cannot purchase it anywhere."
Also, Philips told me,
"We do not have available information about the average life duration of the built-in battery."
Basically, Philips is saying they do not know how long the device will last and there is no way to fix it once the battery dies.
Do you want to invest your money to something that may become useless in a month?????
