After having played some games like Skyrim on my laptop using this controller, I was very happy with it, despite it taking slightly more processing power than using a keyboard and mouse (Skyrim dropped from 40fps on high settings to 36fps). Later that day, me and two other people wanted to play FIFA on the Xbox together, but only had two wireless controllers. I took the chance as I had nothing to lose, and plugged it into the Xbox's USB port (This was an Xbox 360 Elite 120GB, not the current slim model, but it'll probably work on that too), and it worked instantly with no installation. It is now the main controller I use, as I was going to get a new one for my PC and Xbox, but as this one works on both, I can use it on both and the newer controller model is much better than the old black wireless one that came with the Elite console. Plus, the cable is huge and reaches across the living room with ease, so I don't mind at all that it isn't wireless. Overall, I'm pleased with the product.
