Perfect for what I needed. Blocks out the unwanted light coming through the sides of my blinds. My only regret is that I didn't order 2 sets. Also great customer service.

Blocks the light as advertised. Removable style allows for some minor adjustments in position next to shade.

We are having an issue with one window were the shade goes down partway and then stops. You can see the pencil mark where it does stick. After a number of attempts, I removed the track so the shade can go down all the way.. There is a very small amount of light that does come through on the sides and bottoms of the windows . Can you suggest what to put in at the top of the shade to block out the light, that would be helpful. Thanks.
