This gives off a beautiful rainbow reflection when the sun hits it just right.  I got this for making window decals with my Circuit and the decal worked perfectly.  Then I used the rest to help block out the open wind in my office for privacy when I work early mornings or late at night.  It was easy to move and reapply and I love the look it gives.  You get the brightness for the sun but you don’t get people driving by looking into your windows.
