the support is made of cast aluminum and not aluminum. the ball is plastic. the assembly is done poorly, leading games so noise when vibration. the screws are too short, the collar is suitable for driving it 20 years ago (round) while the majority of existing steering wheels are ovoid. the rubber band is too thick and mounting without the leather abyss in 3 movements. product unsatisfactory for the price (even discounted).
only good point compared to many other models, the ball is centered on the support thus on the wheel.
