Rarely used, in working condition, no marks on the screen, some on the plastic casing. Portable laptop screen that attaches the back of a laptop screen to give duel screen. It attaches via 4 included magnets (best to use own strong adhesive to attach magnets to your laptop, came with adhesive pads to stick the magnets to the laptop lid but they aren't strong enough to hold the weight of the screen, so the screen would fall off with the magnets attached) and slides out or can stand alone, connects via a single included usb-c cable or via usb-A with included adapter for power and signal or external power and just signal. Also works with some other mobile devices that have desktop mode such as Samsung DeX).
