For 2 pounds I wondered if there was a difference between the Official Nintendo one which is 15 pounds. Since the Nintendo one doesn't serve tea I assume it is exactly the same.
At first I had trouble with it because I had put the cables into the wrong holes. The reason is because there are two red cables and one is audio and the other video so a switch around and all is working.
I'm not sure about difference except it looks a lot more saturated and colorful. I noticed an odd flicker around my character in a menu selection screen but in the actual game is seems fine.
Overall I'd get this over the official one.
