it really well positioner. Not easy to hang, you have to arrange to fit around the headrest (by making several turns and passing in the middle of the two bars which hold the headrest in order to attach it) but doable. Then you have come to put it in the right angle to be able to see the baby in the rearview mirror. It is also feasible but must still allow 10 minutes to install. Once installed, this is perfect, we can see our child. No reverse magnifying glass mode (very small) as with some other mirrors (square)! Moreover, it does not move, or passing over bumps or the vibrations. Phew! But be careful! It is essential to avoid touching the on entering the car (if passengers) or by attaching baby because after hassle to find the right angle to again be able to see the baby in retro!
