Since our child can often be cared for only one person, so that they sometimes have to leave the room, we need a play pen. This should not be too small. That is why we opted for this playpen. However, the sixteenth-shaped building did not fit so well into the living room, I have a play pen transformed into a rectangle. This is for the product but nir possible when drilling further holes in the floor panels. It would be better if the floor panels from the factory already contained more holes that would allow construction in other variants. Then you can expand the playpens also required or be back (which in a hexagon) is not possible. We use sometimes the large rectangle and sometimes only the small square. Conclusion: good in principle, but with potential for improvement.
