These curtains are what I had in mind for blocking strong sun rays and heat.  The color is calming and blends well with the decor.  As everyone else stated, there is a slight amount of light that can be seen as they do not put you in complete darkness.  This is not a problem for me; I got what I expected.  There were some minor wrinkles that have released on there own while hanging.  I am completely happy with this purchase and would buy them again.

Pros: Keeps heat out; good for Florida sun
Cons: None
