We have tall, large windows in our house and great views that we didn't want to cover up with plantation shutters like all the other windows in our house, but wanted a solution that would allow us to sleep and not let too much sunlight from the sunrise and also keep the hot sun out.  These were perfect so we could sleep soundly and pull the curtains back when we wanted the light and views.  The only reason it was 4 stars was bc initially I had received the incorrect size.
