Improves the handling of the 3DS

This wheel is excellent: it improves the grip and feel of the 3DS. That goes for Mario Kart 7 but also for games requiring reflex (Super Street Fighter IV 3D Edition, Fifa 2012 or other football games ...)
The 3DS fits easily, soft gums allow the stall perfectly. Then, the wheel has large buttons L and R at the back, which rely on real (small) L and R buttons on the console. It is more enjoyable, even for those who do not use the gyroscope in Mario Kart 7.
An excellent choice, especially for those with large hands!
