It works perfectly both for DVD's plus files on USB stick. Picture is perfect. Not a mark on the screen or interior when opened. It was 'Grade C' so very minor scuffs on the lid which 5 minutes with some silver polish made it look like new. Sound not loud and a bit tinny but expected from those tiny speakers. Headphones give super sound. I also have a small battery speaker/amplifier which gives super sound from the headphone socket. This was a good buy and a snip at the price.
