They were fairly easy to install. We did have to loosen a screw on the mounted hardware  pivot it slightly to be able to get the rod into the hardware’s mounting hole bc the recommended 14 inch space from the sill’s top was too tight. 
There’s a fairly big gap around the edges, as you can see in my pic where the daylight streams from behind the blind, but it’s not a dealbreaker. My other pic shows it in the evening with a valance added over. I am happy  would buy these again.
