Summary: I just got Windows 8 and I have not found a way to get the controller to work. I installed the driver from the website and when I plug in the controller, it says the driver could not be loaded and the controller input does not work.

When it worked though, it was pretty good.
Summary: So let's begin with the pros, and some of these may have been mentioned by others: Inexpensive, non-shoddy construction. The analog sticks have a great "click" when pressed, and the face buttons have a distinct depressed feel. Also, I am a big fan of the very long cable, too. The analog sticks snap straight back to the center upon release. The resistance of my two sticks are slightly different, but it's near negligible.
