The rating is negative. During installation, the anchor was torn off in the corner, glued, overheated and somehow plugged into a baguette. The PVC film was torn in two places and redone again, glued and somehow plugged into a baguette. The joints of the baguettes did not dock and deflections formed on the ceiling. The baguettes were fixed crookedly, and cracks of different widths were formed. The craftsmen are not experienced and not accurate.
