We have this stair gate acquired a total of 3 times. The first structure is a bit complicated, but once you understood how it works. The customization options are quite flexible and should cover many installation situations. We holds the terminal eg stable even at a grand staircase bannister upright. The spacers on the drilling side help installation hurdles to overcome. The build quality is the bottom line well. The wood is quite massive and the production quality useful. However, probably not universal because of the grid drops slightly (knotholes in a bar). That would have to be replaced at the quality test. Because it works, we have to keep it but.
Really bad are the wall plugs. Here is to use and not to use the supplied highly recommended higher quality plugs. This saves a lot of hassle.
