While I was looking for clamping roller blinds, but still let me seduce to buy this. And I do not regret it!
I have the blinds directly attached to the window, which was very easy and absolutely secure holding =)
The cables are all right, but that did not bother me.
Since not complete by fastening the blinds directly at the window, always some light coming through on the sides, is for me, but not bad.
Cable works perfectly and I must say they look really good!
I purchased the blinds for my bedroom, because I wanted it a little darker at night and I have no blinds on the windows. Despite lantern outside my window make these blinds pleasantly dark in the room.
thumbs up!
