The first month nothing wrong, suddenly we bought another for the second car. Then with the cold of winter, heating inside the troubles began.

We got rid of the day my daughter took four months on the head .... While the extensible arm is super convenient to modulate and allows good visibility if I can give you a tip opt for a retro monitoring that attaches to the headrest
