Right out of the box it worked as described. It only needs about 1 1/2 inches of clearance from the bottom of the headrest to work. It fits comfortably between the seat back and the underside of the headrest. Also keeps the tablet away from the back of the seat which I needed. It is also possible to tilt the tablet in the 3rd row to show too many range positions. Yay!
