Why does it matter, and why is it so important to you? Does it change anything?
It was the only adapter I could buy at Juice in Florence, Italy (where I bought the laptop) that had HDMI at the time.
The laptop was EUR 1799 ($2,150), the dongle was EUR 89.
After 2-3 months the keyboard started failing. It was replaced by Apple--along with the battery which they found out was faulty, and it started failing again (missed keystrokes, registering twice) after a short while. They replace it _again_, then after 3 days the logic board dies, taking all data with it. Apple replaced it, I sold that piece of shit of a laptop for EUR 1,000, and the guy called me after 2-3 days that the logic board died again and Juice (no Apple Store in his area) would give him a new one.
That was my about 5th and last Apple laptop.
I read lots of reports of these things happening to lots of people, but not getting a lot of attention anywhere for some reason, despite the fact that those things cost $2000 and you should absolutely be able to type for more than 2-3 months without replacing the keyboard.
