The shade darkens really great from, even during the day! Here you should make sure, as close as possible to install the roller blind on the wall or in front of the window. Otherwise too much light coming through on the sides.
What I find not good that Rollo is after some time on the sides, despite fairly heavy plastic rod end, very wavy (see pictures that I have uploaded). So naturally comes through more light on the sides. Also a bit annoying that plastic rod rattles very loudly on the wall when it's windy. But here is less the blind something about it.
4/5 stars as Rollo is wavy with respect to time and a little frayed.
