Happy owner of an ASUS Transformer T100TA, I was soon hampered by the fact that there is only one usb3 port. This hub has the advantage of providing the ASUS 4-port! Another advantage is decisive for me: the 4 USB ports are divided into "square", rather than in on as many hubs. The USB peripherals (USB key, hard disk, mouse, etc.) does "bother" not, as is often the case with usb taken insufficiently aligned and spaced. The hub manages the power supply ports and allows my hard work without worry. This article corresponds to my expectations, I would have just liked a little smaller (it measures 7 cm side for 1 cm thick), hence 4 stars "only". I recommend it!
