With cosi mounted on the rear seats, that's the accessory that allows you to monitor baby from the front and thereby reassuring parents (or see vomit!).
The mirror is lmost off, leaving the flexibility for installation.
This is a little less well which earned him a star: it is a strap to wrap around the rear headrests. The strap is excessively long (this is better than not enough!) And finally, it is quite hard to tighten. But ultimately this is due between the plate and the strap without moving and without vibration.
Once installed, must touch it!
A model that clipserait on the stem of the headrest would be ideal (model of the same manufacturer with light and remote control I think)
