"[T]he stellar performance and added connection features, including Ethernet and Thunderbolt, make it a powerful and functional monitor for users of Thunderbolt-enabled Macs." -- CNET
Up for sale is a used Apple Thunderbolt Display, model A1407. This Thunderbolt 2 dock and monitor combo features a brilliant 2560x1440p display, a bunch of useful ports, and is compatible with all Mac systems that contain a Thunderbolt 2 or 3 (with adapter, not included) port. It is also compatible with Windows PCs which have Thunderbolt 2 or 3 (with adapter) support, though it was not generally sold as such.
This particular unit is in excellent condition, but does have some tearing around the base of the Thunderbolt cable. It is fully functional and ready for use, at a great price!
