Very nice port replicator for MacBook Pro. Possibly the best one at the moment. All ports work fine and to the specification. Beware, HDMI port gives you 4K resolution only at 30Hz (you can actually see lower quality comparing to 60Hz). I see no reason for that old port to exist on this nice device. Another observation is that this drive is thinner than the MacBook pro itself so it hangs in the air when inserted properly. Doesn't cause an issue for me now but can see how it may become an issue in the future.
