## Description

Buy

Review: Great product, full USB 3 - Great product, full USB 3.0 speed through hub and included power adapter means that I know I won't draw too much current for one port. FYI, it does work quite happily as a hub and with ethernet functionality without the power supply but I've not tried this with much data throughput. Powered, the ethernet port is fast enough to (almost) saturate a gigabit connection (~110MB/sec) but I am almost certain this is due to overheads, cable length and other networking variables which are of no fault of the hub.
Review: Probably excellent, but not capabale of providing an independent Ethernet to USB connection - This was bought to provide me with a means of connecting a USB printer to the Ethernet, so all our home machines could print to it without having to leave a dedicated PC running, or an NAS drive. The specification says it can communicate bi-directionally, but at n point does it say it has to be plugged into a computer USB socket to operate. For this reason, I had to send it back. Had I wanted a fast adaptor to plug into a device without a USB3 port, ort an Ethernet port, then it would have been great, Quality was good, and it was very small.

*by A***E on 1 July 2015*

Very nice product. The Ethernet did require drivers for my MacBook Pro Yosemite 10.10 - but no problem. They came down fine and installed and worked perfectly. My only criticism is that the blue LED on the back is very bright indeed and almost lights up the room at night :-)
