The website describes the venetian blinds for roof windows as being "easy to install;" "just click in." THEY ARE NOT EASY TO INSTALL. And the instructions provided are useless because they do not show clearly the correct orientation of the blinds to the window. You would do better to encourage customers to buy from a certified installer rather than try to do it themselves.
