I did not use it but I think it could be useful for someone.
Recently purchased a 9” screen and found that the windscreen mountings were not suitable for my car. Therefore I purchased this. As has been mentioned before on other reviews that having this for a larger screen can cause the screen to wobble around on uneven road. I have rectified this issue by adding a tie between the mount and air vent. Well made item from a good company.
