Giving away two Apple Thunderbolt Displays. I've had them for about 6 years and they had a single owner before that. Only getting rid of them because my company bought me 4k replacements.
27" 2560x1440
Three powered USB 2.0 ports
FireWire 800 port
Gigabit Ethernet port
Thunderbolt port
Kensington security slot
Both are working but occasionally have intermittent flicker. Speakers sound great, cameras work, USB ports all work. I've always used them in a daisy chain setup. They seem to work better on older Macs since Apple pushed a software update that made Thunderbolt behave differently on OS11.
One of the two has a frayed rubber casing on the Thunderbolt cable but it doesn't seem to impact performance.
