I had before mirrors films on windows, normally in daylight it allowed to see outside without being seen. However, I find that they darkened the room and more for someone who lives in the ground floor must always watch the sunset as the night the opposite is true, that is the inside which was the mirror and it is seen from the outside. In short, I did not like. With this frosted film, we do not see anything or inside or outside even the shadow but the advantage is that it does not hide any of the light, it does not darken. For me I did not want to watch the passers so it suits me well, there are privacy without darkening effect. Although satisfied.
