I am really disappointed: I had tentatively ordered three frames, which pleased us very well, because they made a high-quality impression. So I ordered another 30 to equip our whole house with it. Now look to the back of the frame already at more rust - of course it is a place that can not be seen after installation of LED spotlights, but it testifies but of very poor quality Too bad! So at least for wet rooms, I would definitely advise against this framework - unless I caught a faulty batch ...
