"This is a true port replicator that fits the docking slot that is on the bottom of many lenovo business laptops. Easy to attach and detach your laptop, while leaving connections at your desk connected to the replicator. Comes with its own power supply, so if you were going to get a 2nd power supply anyways, might as well just get the whole port replicator for just a bit more money. I find it better than the USB dock because video output of the replicator is true unmodified VGA, thus you get all original quality signal on your HD monitor. With the USB doc, the VGA output from the laptop is first converted to digital, and that leads to lags in video. Unlike the USB replicator, no drivers are needed.

"I have this port and an X230T. They do not match up, so it is completely unusable."
