The only problem was that it arrived in pieces, impossible to assemble, which made it very difficult for us to place it.

Unacceptable compared to others on the market.
First of all, it is not completely clear that it is not meant to be mounted on a wall and is ONLY for hanging on doors/windows, and that too with plastic hooks. The bottom rail, which acts as a counterweight, does not secure anywhere and falls off. I asked both the store and the company abroad to buy additional metal accessories that are more stable/durable to mount it on a wall, and absolutely nothing. Three of these, useless, wasted money, and if anyone looks beyond the surface to have a good and clear picture, they will realize that there are infinitely better options available on the market.
