I ordered 6 sets of these curtains for the main level of my home.  I wanted something sheer enough to allow the natural light I get to filter in.  These work very well for that.  As they are sheer, if you're looking for something to maintain privacy, you won't be happy with these.  You can't see in clearly, but you are able to make out shadows.  That personally doesn't bother me.  You could always pair these with a heavier curtain and for privacy at night if you wanted.  These would accent very well with that, however you would need a double rod to do so.  I love the grommets at the top, it fits my whole décor and I am very happy with them.
