Handy little unit comprising ethernet, 2x USB 3.0 ports and SD/Micro SD card reader, saves me space on my computer desk as have this connected to my pc. Does exactly as it should do except i havent tried the ethernet connection as i have no need for it, just plug and play windows will find the drivers auto. Usual plastic box feel though so thnk the £20 price tag is a little high for what it is.
