I've personally upgraded to the bigger ts3 plus dock but this one had quite little use and worked great. It's rare two have two display outs via one cable working for the m series apple macbooks.

Macbook compatibility for 2 display outs is a bit complex to list here, if it supports two displays it will support 2 displays out of this dock with the one thunderbolt conneciton.

Otherwise it has two usb's and an ethernet connection.
