I opted for this grid, because the grid would have been Avant too big for our stairs. We are delighted with this solution. The technique is simple, the assembly declared simply and super. In Lascal.de there's even a video. Okay, it makes a louder noise when furling, and we think that this was for security reasons, but if the child has opened the grille, thought. But Conclusion: some folds down for compact and above all a solution without tripping hazard (as they otherwise occur in each grid) we would not otherwise have found. We are super happy! PS The grid can be opened with one hand and close. Maybe it's the attachment (there are different ways), we have in any case no problems. We buy recommendation!
