It is very good, lightweight construction, does not restrict lighting (I chose transparent panels). The arms are sturdy and their material is of good quality, which makes the whole construction stable. Installation requires basic knowledge (wall drilling, leveling, sealing polycarbonate, etc.), and the help of another person, especially in the installation of the second piece. The final aesthetic result is excellent. The only thing left is to test its durability over time and in weather conditions (sun, rain, wind).
