I have made the sun blind with the suction cups firmly to the window, holding. The blinds can be rolled back with a side button. Contactor sufficiently against the sun; but could be a little wider. The attachment to the window does not work with me. The wheel sensor not ruled and the window does not automatically moves down, however, remain the clips in the rubber plug from the window and go thus not down that is at full speed flying one the things well to the ears.
