This is a portable player, but the lithium battery is dead and has been removed. It can only be used with an adapter. The hinge is loose. The remote control is unusable due to liquid leakage. There are slots for SD cards and USB, but their functionality hasn't been tested. The volume and fast-forward buttons are slow to respond. They react when pressed hard or held down. I've confirmed that it can play DVDs, but I haven't tested it for hours, so it's considered junk. No returns accepted. I'm listing this at a price that barely covers fees and shipping costs. Thank you. - Model: Portable DVD Player - Remote Control: Includes remote control (broken) - Screen Size: Foldable LCD screen - Function: DVD playback - Connection Terminals: External connection terminals available Added September 25, 2025: The instruction manual is included.
