The grille keeps its promises. It's super easy to install and keeps our little whirlwind from which to make the whole apartment uncertain. Wonderfully suitable for the balcony door. You can calm the room sometimes leave for a moment, have to have that little ausbüxt onto the balcony without fear. It is stable and keeps the Rüttelangriffen the little stand, even if you do - as we do - has not anchored with screws in the doorway. All in all to recommend it. Should we once again need a grille, we will resort to this.
