Great product from I ball, i am using a usb 2 port hub from past 3 years and not a single issue till now. When i came across that now i ball i giving usb3 four porthub 100 less in flash sale then i thought i had to grab this one. Trust me i am getting 48 mbps of reading and 28 mbps of writing speed on my usb 3 pendrive on usb 3 port of my laptopp. Also it comes with a direct replacement policy if anything happens internally. So my point is if u want a really fast four port hub you can have usb 3 hub. Keep in mind i ball also has usb 2 4 port hub also.
