The device itself is adequate generally speaking. I primarily wanted it for the cd/dvd being present to play old DVDs I plan to keep. The settings were changed to 'never' shut down when plugged in - but it keeps shutting down completely after a short while. There are supposed to be 2 batteries - but only ONE came with it. That is a fail in my book - unless clearly noted in the description when selling it. It was not.  I would love to receive another battery from the seller. We'll see if I have good news to update this review with!
