Originally bought unit for installing into inside of computer unit, it wouldn't work due to large graphics card. This external model worked perfectly!

Is necesary to have this USB extension in the PC. Is relaxing to work with this possibility ...

I got this for a Dell I7547 laptop (BB SKU 8733545) since it didn't have an Ethernet port. Chose this version since it ALSO doubles as a USB3 hub. Plugged it in to the laptop (wireless was connected), the W8.1 machine quickly downloaded the necessary drivers and worked right away with NO configuration required. Small size, I've confirmed USB 3 speeds and gigabit connection speeds. Very happy.

Easy plug-and-play; nice compact size and love having the capability of connecting Ethernet network cable directly.

I had to buy an adapter for a new laptop without wired networking. I did some research on the options and bounced around with a few options. There are some cheaper options and there are some smaller options, but this one won me over for a couple of reasons. My laptop only has 3 USB ports so using 1 for Ethernet left me with only 2 which isn't really adequate anymore. This is an Ethernet adapter with additional ports so I can solve two problems at once. The ports on the module are USB3 so I'm not sacrificing speed by expanding my USB ports. I've had no problems with Ethernet connectivity or with any of the USB devices I've plugged in. It's a simple product (no external power requirements is a plus too) that does what it's supposed to do.
