I had ordered a roll to test first. Really satisfied, I bought in larger quantities to cover several windows. The plastic film 2 fulfills the qualities I was looking for: - Prevent to see anything through the window, even up close. - Let go still light (to prevent an effect "curtain"!) These are windows of a small room cloakroom made to change and overlooking a busy street. Needless to say that I've looked at 2 times! The power blackout is very important even at night with lighting, one can distinguish the bulbs through. Impossible to distinguish a silhouette or objects through. And day, even if very mild, light passes through and does not give the impression of having transformed the window wall! This is exactly what I wanted.
