This product was provided with a very unclear drawing about how to instal it. The picture of the tools it suggested were just a screwdriver for cross header screws and a flat screwdriver. However the screws provided were not cross header screws they required a Torx screwdriver (Star-Drive). This was also needed to remove the screws already in the window. I did not know such a screwdriver existed and struggled to remove/instal the screws. I had to get my neighbour to help and fortunately he is a builder so knew what was needed. The instructions also were not very clear about the way to attach the blind so it took us 3 attempts to get it to work in the right way! In total this took 2 hours of installation time including watching and rewatching the unhelpful video clip and reading the unclear picture instructions.
