We have to keep the mirror angeshafft to our dwarf during long car trips in mind. The mirror is easy to assemble and easy to adjust with two people. Being alone one has to be a few times to take on and off at the correct angle. The setting works well with no problems. 4 stars only because of the angle for us is not enough. We need the mirror can still continue to tilt sideways. When mounted with us the mirror on the middle headrest or side headrest is unfortunately the bracket from the child seat in the way. Therefore, the star deduction. Otherwise, it served its purpose. Our dwarf looks also like while driving in the mirror to see what's there so going forward.
