On the one hand, I had always problems with the receiver, while a controller worked well, constantly lost the other even at 2m distance connection and built it up again. Extremely annoying if the middle of the game to enter repeatedly exposed for 1-2 seconds. So the controller was slowly useless.
Even worse, it looks at the wear. The sticks are made of such bad material, after a 1-hour game session at the desk were all Gummifussel on the floor. And so it continued until the caps finally completely broke away and the stick was no longer neat to use. This after almost a year in rare use (approximately every 2 weeks for 2-3 hours FIFA).
CONCLUSION: Stay away! rather spend a few euros more for the Xbox 360 Controller. This is by far better quality and poses no problems. Have four of them in operation and no disconnections or otherwise.
For the PS3 Players: From my own experience I can say you get used to fast on the X-Box controller!
