This review is from: Thunderbolt to Gigabit Ethernet Adapter (Personal Computers)
I get it, most people don't plug anything in anymore, so why charge everyone for an ethernet port that would just add thickness to a device. And $30 is a lot to pay for the $5 (if that) of electronics in this thing.
But it works, every time. And when it's for work, why save a few bucks on the knock-off just to have it ruin your day later?
