What People Are Saying About Our Light Blockers for Blinds

Fantastic! Bought them to block the light coming out of the sides of my French door cellular shades. I can enjoy sitting at my desk without the sun hurting my eyes. Lightning fast shipping, arrived safely packaged and installed them in about 5 minutes. Will be back in the future 🙂

I can see where these would work well on shades that weren't measured properly and had a lot of space on each side, but ours were measured so well there is not enough space to put one on each side. Our bedroom faces east so we get the early morning sun and the tiny gap we have with the sun shining on our face wakes us up. These are sturdy and well made. I will recommend them to other people, just did not work for us.
