I previously reviewed this very highly after purchasing it for my Win 7 machine. Have since updated to Win 8 and the controller is now worthless. My system kept freezing up and blue-screening when playing games via Steam, and after a bit of digging found out that the drivers for this controller were causing it. On the official forum for this product, a Snakebyte representative admitted that they are no longer releasing any updates for the driver and will not respond to any more complaints regarding this problem. Well, it was good while it lasted, but with such terrible customer support I will never buy a Snakebyte product again. Avoid at all costs.
