The ability to tighten each of the ball joints will hopefully prevent premature drooping and accidental drops. The carbon fiber stem makes the unit light weight yet sturdy, while reducing some of the vibration. The unit juts out a little too much puting the Tablet a little too close to the user. I also wonder if the unit would be more stable if it attached to both of the head rest posts.
Very well made mount, however, because it is on a single arm, any road vibration in the vehicle makes the display shake. It would be great in a low vibration vehicle, or a vehicle at rest.
