I can't describe to you what relief these curtains brought.
First of all, our neighborhood has tall lantern lights installed on properties (which is great to keep the area lit), but the one in our yard is practically in front of our bedroom windows. Since buying these, our room is 95% darker and it's awesome!

In addition, we have noisy neighbors that are going in and out raucously at all times of the night. These drastically reduced the amount of noise we hear to something barely audible. 

I love these so much and would recommend!
