In ventilation grille of the mobile holder holds very well with me. The terminal, which is plugged into the grille has usefully move two wide slots. depending on the ventilation grille at the car. To switch between the two slots the terminal must simply be rotated 90 °. For my Ventilation of the wider slot was a little too loose, the narrower budge.
