The USB port is close to the speed of change, and an empty pocket or I put sunglasses. My previous USB stick often too long risked tearing. If the USB port is damaged, I dare not imagine the costs at Opel to open the dashboard and access the original audio system ...
With this key, no risk, it exceeds more.
Obviously, it takes a little more careful when removing and inserting, but worth the effort.
Not suitable for office use, or to be transported often, because really very small, it is easily lost.
But the car is perfect, discreet and invisible. And no flashing LED and can be distracting.
