The great advantage of door safety gate is for me is that it requires no drilling and therefore can be changed quickly and without damage between different doors. And this flexibility thwarted the expansion. Because in order to mount it, you have to herausprokeln the plastic inserts on one side of the grid with a strong screwdriver. That would not do it regularly. In addition, the inserts must then be stored somewhere where they go according to experience lost sooner or later. They should have better use for connecting a pin into the hole for the screw, connected with a kind of iron collar which engages externally around the horizontal bars. That would have looked not so elegant and slim, but you could take off again with a handle. Otherwise the extension is shapely and stable and do their duty. Therefore, still 3 stars.
