interesting but...
the connection wire to the computer is a bit short, so it doesn't fit the way you want it to.
The connections are designed to be invisible, good for aesthetics but not practical if plugged in: regular disconnection.
the cable has a direction, if it is not respected, all the functions are not operational. (you just have to locate it with a rubber band and then it's fine).
but apart from that it's very practical and replaces much more expensive proprietary connection boxes.
