This is a junk item. It works, but there is noise on the screen. Sometimes there is no noise, but I don't know what the cause is. Please note that this is a non-return, non-cancel item. Appearance: There are no noticeable stains or scratches on the main unit or display. The keyboard has been used, but it doesn't look dirty. I will hand it over after initialization, with the OS installed. Only the main unit, keyboard, charger, and pen are included.
