The system is very simple:
It straddles the bracket using the two clamping hooks into the rails of the headrest and then fixed them with the respective tabs. For thicker rails there are thinner "Zwischenleg-Gummies". I use myself the thick in my Mercedes Benz C180 (W202).
Then they stretched a tablet by rotating the corresponding switch back to adjust the size.
I tested the brackets using tablets of various sizes.
My 11.6 "tablet with dimensions of 305mmx191mm (width, height) was the largest, which was just chucking still.
Now for the small negative point, the angle of inclination. My front seats are tilted slightly back so that the tablet would have to be relatively flat, so you can relax and look at it. Unfortunately, the angle of inclination is adjustable while, but not so strong that it can compensate for the tilt of the seats.
This is the type of support owed, as these would not be so stable after prolonged arm.
In general, I am very pleasantly surprised by the device, it is solidly built, with value and easy to use. The tilt angle is also specifically a problem my seating position as a driver.
