Works as expected. Both connectors fit snugly. Tested with online speed test and as fast as promised. Plug-and-Play on my travel Chromebook, to bypass slow Wi-Fi networks. It's worth paying a little more to buy a product supported by a company having a physical presence in the North American market.
Make sure you understand the connector that you are getting before you order. I thought all USB would fit. Not so. I had to order this USB to USB-C connector as shown here. Works fine now. I used it to connect my all-in-one to my modem/router direct by ethernet to usb so I could make changes to my modem/router address and channel.
I have a problem with my laptop's Gigabit PCIe Ethernet controller and Windows 10 Anniversary Edition. I have try everything, still my Ethernet connection is stuck at 100Mbps. Buy this device, plug it into my computer and reboot. Windows 10 build a new network connection at 1 gigabit/s in seconds (speed verified with Lan Speed Test). Voilà!! Quick and easy.
