The Speed Wheel fits comfortably in your hand, the bigger trigger switches can be very easy to operate and have a little more leeway compared with the normal controller. So you can very precisely dosed the throttle or brakes.
A disadvantage is that there is no RB / LB shoulder buttons, which eg results in a slightly more cumbersome PGR4 control through the menus or the camera change can be disturbing. Most but even alternative controller layouts offered by the game, so that the "damage" is limited.
For people who like to drive with a manual transmission, but which is likely to have the knock-out criterion be because the switching means Digipad, eg in F1 or 3/4 Forza just feels not good. Therefore, a star deduction for the missing LB / RB shoulder buttons.
If you play with automatic circuit only remains that you have to get used to the unfamiliar holding the Speed Wheels. There is no fixed pivot point here. It deflected by inclining the Speed Wheel greater or lesser extent or in the corresponding direction "turns". That makes for some time even fun. In addition, the Speed Wheel has a vibration feedback as it is known eg from MadCatz steering wheels. True Force Feedback you're looking for though in vain, but the vibrations you can live quite well.
Fatigue occur not more than the game with a steering wheel or controller. At most, a few hours at a time it might be difficult. But that is probably the case everywhere.
The build quality is kept high. It rattles and nothing wobbles, the device works without annoying input lag and it looks cool when "free-floating" a race car around the track chasing) Kinect is not required!
Conclusion
*****
Who shuns the high price of reasonable REAL steering wheels for the Xbox 360 or just do not want / has no place, this constantly assemble and disassemble, the Speed Wheel should definitely take a closer look. For "pros", the device is less suitable because it is just too much and too little steering wheel controller.
I personally like to play offline, either alone or with friends and rarely online, and certainly not in leagues. My MadCatz MC2 is now probably even longer in the closet unused. The Speed Wheel is a good compromise for me and my ideas.
Have Fun!
