I have the Sun Zero Lichtenberg curtains. I choose these, because I wanted some that looked good and that would help darken the room, when we preferred the room darker. My husband works swing shifts, therefore there are times when he is trying to sleep during the day, and prefers the room to be darker, then my previous curtains would allow the room to be during daytime hours. These curtains are stylish and are well made. They were very easy to hang, and when closed they block the bight sunlight from shining into the room, allowing daytime sleepers to sleep better. Also our house tends to be drafty around the windows. These curtains also seem to help with the blocking drifts around the windows.  I am very happy with these curtains.
