Summary: When working with my laptop, the need for more usb ports became obvious. I added this unit to solve that issue and it has satisfied that issue. I was somewhat concerned that the additional 7 ports may cause an overload, which has occurred with a different computer some years ago. No problems have been experienced with this unit whatsoever.
Summary: My unpowered hub had trouble when I plugged in rechargers and all my flight simulator devices. This hub has worked fine, so far, handling those power-hungry devices that do not demand a lot of concurrent high bandwidth communication.
Summary: I bought this unit based on reviews of similar items and I am quite happy with the purchase. I had a need to try and hook up multiple USB devices to my Android stick and, so far, it has worked great. I was able to connect a 1.5 TB hard-drive to the stick and access the media files.
