Bests & Worsts Reviews from Amazon

My work computer has Windows 7, so when I started to run out of ports, I picked this one because it specifically stated it was compatible. Got the package, plugged it in. Nothing worked, even items that were working fine when plugged directly into my computer. Saw no drivers were necessary (nice), so called support. They said this device doesn't work with accessories, like headphones, keyboards, and mice - only USB for data transfer. Why you'd need to transfer data from 4 sources at once is beyond me, as is why they wouldn't support accessories. SMH. Returning.
