GPX Xbox 360 Refined ergonomics for optimal comfort and handling. Non-slip grip on the entire lower surface for enhanced handling and comfort. Optimized precision (2 times greater than that provided by other gamepads on the market), thanks to 16-bit electronics. 2 progressive triggers. Low-frequency vibration motor on the left, and high-frequency motor on the right: lets you feel distinct feedback effects in games, on either the left or right-hand side. A big advantage in real-time gaming! PC-compatible (Windows XP, Vista, 7 and 8).
