I installed this in the bathroom on a window that already had privacy glass because it was the only way I could have any light through the only window into the bathroom since my husband thought it would be more private than just the privacy glass alone and I have other battles to spend energy on. It has restored light to the space and peace to the marriage.  Missing one star because it's incredibly easy for the shade to get kittywampus when pulling down or putting back up - in fact it is guaranteed to go crooked and need to be straightened every pull, no matter how careful I am... perhaps that's a feature since it's just as easy to set straight, but it's annoying.  Otherwise, this is exactly as advertised, and perfect for our needs.
