I have a good piece for some time under observation. But so far was with the price of 300, - too expensive. When I then here it for less than 200 - have found I could not resist. Ingenious part. It has really cleaned up on my desk. Gigabit Lan, sound in and out, 3x USB 3.0, Thunderbolt and FireWire. About only 1 cable. So it must be. Unfortunately, no Thunderbolt cable lies. These cables are outrageously expensive because of high royalties from Apple. But it was worth it all.
