This Joby Action Series JB01330 suction cup and locking arm allow you to securely mount your compatible action video camera to your vehicle, so you can capture clear point-of-view footage with minimal vibration.
The build quality is amazing and the suction cup gets extremely tight. I needed this mount for my car and couldn't be happier. As long the threads are secured and the suction cup is engaged, you're good to go. Also It is very easy to adjust since it has a ball joint on both ends.
I haven't tried Joby's action adapter kit yet, but I am going to. My assumption is that if you use their tripod buckle adapter you'll get better audio/video since it is compatible with the anti-vibration insert.
