Review: Work as they should. - These are fantastic. Don't let you husband install.
Review: Real blackout - Absolute game changer. Working night shift means needing good blackout during the daytime, that annoying strip of light to the side of the roller shades always bothered me. After installing these the room is completely dark. It’s sleek enough and doesn’t take away from the room decor. Easy to install, just peel and stick. It can be trimmed to fit the length of your window but since the material is thick it’s a bit difficult to cut. Don’t expect to use a kitchen scissors, I ended up using a utility knife and even then it was a task but I guess if it were thinner then it would be too flimsy

### ⭐⭐⭐⭐⭐ Work as they should.

### ⭐⭐⭐⭐⭐ Real blackout
*by K***N on August 28, 2024*

Absolute game changer. Working night shift means needing good blackout during the daytime, that annoying strip of light to the side of the roller shades always bothered me. After installing these the room is completely dark. It’s sleek enough and doesn’t take away from the room decor. Easy to install, just peel and stick.

### ⭐⭐⭐⭐ Brilliantly simple fix for those pesky light leaking gaps
*by A***E on April 2, 2024*

GREATLY reduces light leaks around the edges of blackout shades. Let there be darkness! One star taken off for value for money. Seems a bit pricey for the materials involved, but otherwise, five stars. Also, not trivial to fit around the blind brackets, and requires modification (i.e. cutting up) for satisfactory results - but that's not the fault of this product. Ideally, you'd leave a SLIGHT (1/8") gap on both sides of your made-to-measure blackout shades when installing to allow room for these to go in with less fuss, but if we're talking "ideally," ideally the shade companies would license these and sell them to you as an option up front.
