This is an adaptive spinner knob that enables smooth, comfortable one-handed use of the steering wheel for someone with good grip. It enables the driver to be able to turn the steering wheel from the knob instead of turning the wheel itself. Spinner knobs are made out of durable materials that last for long periods of time and they are also easy to install. For both left and right-handed drivers.
Caution: Using hand control devices on the steering wheel can require some practice. They give significant mechanical advantage in turns however, drivers can easily oversteer in cornering. Also, activating the turn signals while using a spinner or hand control can be difficult to master, as the hand must remain on the handle at all times.
