Redi Shade No Tools Easy Lift Trim-at-Home Cordless Cellular Blackout Fabric Shade Natural, 30" W x 64" L, (Fits windows 19"- 30")

Don't buy unless you can solve problem of adhesion.Love everything about them...ease of installation, blackout feature, ease of use and maintenance and still look pretty but for adhesion issue from the first. Adding more adhesive, trying double sided tape, super glue, NONE of it worked. Everytime I think my "fix" did the trick I am back to squre one two days later.It is not the window frame but the adhesive used by the company as it is always the same, but different location on each shade, that start to sag a couple days later and my fixes are still attached to window sash/frame.I bought 2 and I am on a fixed income so buying new ones not an option at this price. I have also wished the company offered a fix.

A waste of money, a hassle, and damaged plaster. Do not buy these. There are permanent but easy to install blinds that cost the same and work much better. I thought I would save myself some work, and ended up tripling the work. I have bought two of these before in the light filtering version. Those work ok except one had bad adhesive which I fixed with 3M temporary hanging strips. Both of these still work, possibly because they are lighter (weight wise) and in rooms where we don't put them up and down often. These blackout ones are a mess. They are too heavy first of all, which causes the adhesive to totally fail, but the adhesive is still strong enough to pull the paint and plaster off of walls (worst of both worlds). Also, the material is more resistant to pulling, so 1) both blinds I bought would no lower all the way (5-8 inches less than they should (leaving lots of space for light to come in- sorta defeats the purpose of blackout) and 2) puts more tension on the adhesive when you pull. The blackout version also is not as good looking as the light filtering is - looks way cheaper.The other big problem is that both blinds I ordered had defective cordless up/down mechanisms that were not noticable until they were actually hung. Both hung crooked (VERY crooked) when up OR down no matter how much troubleshooting I did. The bigger issue is that the company won't take returns if they have been cut and hung. Their warranty has so many loopholes that there is basically no real warranty and the company is not reachable by email or phone. Your only option is an online chatbot on their website that doesn't always appear on pages and will just blow you off without allowing you to write to a real person.The process I had to go through to get this resolved was OFFENSIVE from both Amazon and the company (which did ZERO) and I still had to pony up to get my plaster and paint fixed. Avoid these at all costs.

Keeping in mind these are very affordable blackout shades I did have a couple challenges with these. The first is the cutting is not very easy, especially in my case I was only cutting about an inch off the total width. The second is the adhesion did not work well for me. My window ledge was a little more narrow so the full adhesion strip was not making contact (maybe 2/3 touching). As a result of this and heat they wouldn't stay up 24 hours. I ended up stapling them up, via staple gun. That did the trick. They look decent, block light, and seems to reduce sun heat. If you're not pulling them down right in the center they will get a little lopsided, but can be adjusted. The best feature is they are easy to use.

A little surprised by the negative reviews here, elsewhere almost five stars which is what I will give them. I think they are awesome especially after having installed regular ones previously. I agree that the instructions should tell you you need a really sharp knife, I also tried many and sharpened one before I finally was able to cut through. So that was not as easy as they said but still do able. Also the plastic guide is really nice but you have to tAke it off once you get to the bottom plastic that needs cutting to cut that part. At first I thought that the material was just paper cause it kinda looks like it but I tried ripping a piece from what I'd cut off and it's very strong, I could not tear it. Honestly my more expensive ones kind of resemble paper also. They don't look cheap up at all. The inside is lined shiny silver to block the sun so it does give these a pale gray hue which pleases me cause I was looking for gray ones! But if you want stark white these are not. I dont care if the adhesive doesn't stick, I will just use the 3m Velcro if not. ESP for this price. I actually ordered two more!
