If you have an ultrabook without ethernet, you need this!

Summary: Despite the fact that my laptop, a Fujitsu Lifebook U904 has a ethernet port built in, a feat for a ultrabook, I didn't want to risk breaking it. It's one of those slide out and pop open gizmos that seems like it would break, then cost a fortune to fix. I'd much rather carry around a dongle than risk breaking anything.
Summary: I got this USB network adapter because my laptop RJ45 jack is not working anymore. At my place i don't really use it but at office intranet works via wire network. I got it on time and properly packed.
