I bought this for use with my MacBook Pro, and I'm disappointed. At first glance, the hub lives up to all of its claims, but when I use it as a cabled ethernet adapter and power relay, it overheats after a couple of hours, and at that point it effectively disconnects the power from the MacBook, but continues to *draw* power from the battery. So if that happens overnight, the battery is dead by morning. So overall, good for short-term use (up to a couple hours), but not for all-day use.
