OK this is a little device for special users and there are not to many out there that will need this but I am sure there are some.
This is a 3 port USB HUB nothing special there the USB ports swivel so that it will be easier to plug your USB devices in. But it is more then just a HUB.
Next to the USB ports it also offers an RJ45 network port. If you computer is missing an physical network port then this could be the solution. For instance if you have a Macbook Air with only 1 USB port then this is great it gives you a real network port and 3 USB ports instead of one.
