In operation itself can easily align the game. So far as I could find no problems, that the mirror changes its position while driving. The mirror surface itself might be a bit bigger, but thanks to the movable joint that is not an issue.
Conclusion #
A fine baby mirror, that can be mounted with little tool. If you have done this once, take off the hanging and yet 30 more seconds. What I like most, that the headrests do not need to expand anyway, so since the mirror can be attached.
