Since I have 2 children and the larger even sitting in a car seat, I had to fix the mirror in the middle.
For mounting, it is best on the trunk, since the mirror is mounted with the fastening straps on the head part. He was very easy to attach and adjust the, was not difficult.
So pure, buckle up and going on Maxi Cosi from my younger son went journey :-)
I must say that this mirror very practical, you can see through even the back, although the mirror in the middle of a slope.
And the best part was that I saw my son completely, I saw the whole seat Maxi Cosi + + child. You could watch everything very good.
Then there was the size even net times as bad. After all, some levels are really very small and you can see nothing pure.
So I can really recommend this mirror.
