Review on 🪟 Effortless Lift Select Trim-at-Home Cellular Shade 36"x64" - Light Filtering, Cordless, White (Fits 19"-36" Windows) by Angel Young

you get what you pay for. There's a reason they were the cheapest. That being said, they're doing their job, at least for now. How long they will last is not known. They "stick" to the top of the window. Not all wall surfaces are suitable for gluing. If they don't stick, there is no alternative method of attachment. The instructions say to remove the bright red stickers on the bottom that tell the dimensions. It turned out to be quite a hassle, it was quite difficult to remove, and the paper kept tearing. When I came up with the idea of loosening the glue with a warm hair dryer, it was child's play. A lot can go wrong during installation, but if your stars are right, you can't beat the price.
