The end of the cable with the Thunderbolt connector is not in great shape (see photo), but my experience with it has been that if you don't disturb the cable after connecting it, it will work fine. Other than that, the monitor is very close to new condition. The item "Apple Thunderbolt A1407 27 Widescreen LCD Monitor, built-in Speakers" is in sale since Sunday, January 29, 2017.
