Summary: I purchased this controller to use with Steam Big Picture for games that were better with a controller. It's a simple, quick alternative to setting up a PS3 controller with drivers. The controller is exactly the same as a standard 360 controller. The wired version was fine for me, as I play on my desk. However, if you want to play in your living room, the wireless controller might be a better option.
Summary: I bought this for a game that I had (Raymans Raging Rabbids pack) to see if I could play some of the games better. No really. I am not an xbox user/owner so find the controls a bit sensitive and hard to get used to despite calibration and adjustment. I couldn't get the shock feedback to work but maybe because my game(s) don't really support it.
Pros: Easy to setup, works
Cons: SOftware doesn't seem to fully support all the functions
Summary: Even though it came with drivers, none were needed. Everything automatically detected in windows 7 and the games instantly recognized the controller without having to map buttons. For anyone wondering what the difference between this and the "Microsoft Xbox 360 Wired Controller" going for $35 its that this one comes with a driver disc.
